Often enough. It can be quite fun. You can use the using statement to declare a name for a more complex type, example:
using ThreadPool =
System.Collections.Concurrent.ConcurrentBag<System.Tuple<System.Threading.Semaphore,
System.Collections.Concurrent.ConcurrentQueue<System.Action>, System.Action<System.Exception>>>;
but it's cumbersome, and this is where F# really shines[^]
Example from my article I linked above:
type Work = unit -> unit
type ThreadExceptionHandler = Exception -> unit
type ThreadGate = Semaphore
type ThreadQueue = ConcurrentQueue<Work>
type AThread = ThreadGate * ThreadQueue * ThreadExceptionHandler
type ThreadPool = ConcurrentBag<AThread>

yeah i really wish there were something in C# as flexible as typedef in C++. Using has too many limitations when it comes to declaring templates (for example no templated usings)
When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.

I'm reading a lighter book right now and it is fantastic. It hits on a lot of things I'm interested in.
The Setup 40-something psychologist / university prof with no musical skills but a lot of desire plays Guitar Hero and becomes mediocre at it. He then wonders, "hey, could I learn to play the guitar? Could I learn to play it well?" The journey ensues.
If you're interested in how we learn in general, music, music theory and practice and/or guitars you will like this book.

What I find funny is all of my friends who actually play the guitar and have tried the game say they are horrible at Guitar Hero. I don't bother with the game - I prefer the real thing.

I know. Same thing here. Been playing Guitar for a long time but terrible at Guitar Hero.
The author's experience is a bit different because he started with Guitar Hero and went to the Guitar. Basically leveraging only the rhythm / syncopation of press buttons on Guitar Hero.

Rhythm is an issue for many musicians people who play music.

I play bass, upright and electric, and tried GH at a friend's house. Bass instruments are usually slower to speak, so you have to start the note a little early if you want the sound to start on time. The program complained about every note until I tried deliberately playing each note late.

Playing the guitar like playing Guitar Hero is simply a motor skill. Anyone can do it with practice. It takes more practice to play Through the fire and flames than it does to play Slow ride.

I didnt see 'Guitar Hero' mentioned on that page at all, but anyway, it isnt a real instrument at all of course.
However I do think we all have musical ability, to greater and lesser degrees, and anyone can learn an instrument.

I agree. That's why I'm finding the author's study of the subject so fascinating since he started so late in life (and many people believe that is a problem, while brain plasticity suggests otherwise.)

I read somewhere that it is a myth that we can not learn new skills in later life. I think motivation and energy is the real limiting factor.

I'm just looking for some general advice I can offer my friend who's in a tricky predicament involving a project he hired a software company to develop for him.
A few days ago, my friend calls me in a panic to see if I can help resolve an issue he's having. He owns a small business in the medical industry & hired a software company to develop some software for his business. Development started about 9 months ago, using AngularJS. This software company got about halfway through development before their sole developer who was working on the project left & they needed to hire a new developer. For some reason, this new developer informed the software company the entire project needed to be upgraded to Angular 4, and the company agreed to move forward with the upgrade (at this point, I don't know the specifics as to why this was decided). This developer then left the company as well. Fast forward to now & 1 or 2 additional developers who have come and gone, & the application is now a mess & they're telling my friend they're stuck & not sure how to move forward.
The trouble seems to be about 10,000 lines of code which was originally written in AngularJS, which contains crucial medical info & very delicate medical rules that cannot be incorrect & the software company's been unable to upgrade this code into Angular 4.
So, after speaking with my friend, I've offered to at least speak with the current developer to see his pain points but I'm curious if there's any advice anyone can give as to best handle this situation?
They've already developed a great deal in Angular 4, but for some reason, can't upgrade about 10,000 lines of Angular JS code. Do I recommend they revert everything back to AngularJS & redevelop anything they've written in Angular 4, back into AngularJS? Do I say they just need to keep trudging through this code and make it work? Do I simply say they're out of luck?
I know this is a very general question but just looking for some general advice or questions I should ask them. I have a call with them today to figure out more details as to what's going on.
Thanks in advance.

This software company is willing to talk about how their project is elephanted up and take resolution advice from a complete stranger? I agree with Griff.

I think that the bold part above should invite extreme concern. If the code cannot be ported to another language I would be asking - "Where are the unit tests?" It should be possible to port the code and via the existing and new unit tests prove that the new code is not broken.
If the answer comes back that "There are no unit tests" then the integrity of the "very delicate medical rules" comes into question and with it the whole of the project.

Of course it can be upgraded. Someone is lying or stupid.

Thank goodness for that, sometimes the blindingly obvious just slips past me.

He hired a company; how the company divides the work and retains employees is up to that company.

Just ask him how long would it take to finish the migration of the 10,000 lines of code after his review to the Angular 4,then you can ask your friend in the business if that timeline is acceptable to him.

There are a lot of signs as to what is wrong:
1. Goalie35 wrote: AngularJS, which contains crucial medical info & very delicate medical rules
That is huge flag that things are incorrect. AngularJS is technology for front-ends. It's really just VIEW code. But the developers have mixed in the business rules and business logic that should have been safely nestled away in the back-end with no worries about what was displaying (angularjs) the data.
That's quite terrible really. This is a big point because it proves the original devs had no idea what they were doing.
2. Goalie35 wrote: 10,000 lines of code which was originally written in AngularJS
10,000 lines of code!!! Another flag that something is very likely wrong.
This is just the VIEW code and it is 10,000 lines long.
A little math puts it in context: 10,000 / 50 lines (8.5x11 - approximate) = 200 pages of code.
Oy!!
These are just indications that there were many bad ideas involved.
That is why devs are fleeing the project.
You should ask them:
1. Why was business logic and bus. rules mixed on the View?
2. Why did it take 10,000 lines of code?
3. Why wasn't there any oversight of the original dev?

Good point. It also means the business rules are being shipped to the user in the browser.

Unless you actually want to get suckered into that project...I'd say run. Don't even offer any sort of advice, because if they're truly elephanted, they're going to see you as their savior, and next thing you know they'll be offering you what might appear at first like a big fat chunk of change but will turn out to be a living nightmare.
Of course I know nothing about the situation beyond what you've already written...but I'd be extra paranoid about this sort of thing. You've already raised the red flags yourself: Two developers have already taken a stab at it and quit...

I think the logical thing to do is to rebuild this, using Angular or React, from scratch. Probably Angular, but a NEW project that can willingly copy old code, but never accidentally inherits anything that's not been vetted

AngularJS is in maintenance, it should never have been used. they should never revert. There is no such thing as AngularJS code that can't be ported to Angular4 (although it's up to 7, why are they on 4?)
