The job's a game
And every task you undertake
Becomes a piece of cake
A lark! A spree! It's very clear to see that
A spoonful of sugar helps the medicine go down
The medicine go down, the medicine go down
Just a spoonful of sugar helps the medicine go down
In a most delightful way

That's really amusing. I got an email from some code regarding a very similar issue and how to fix it.
I didn't quite buy the fix, it seemed odd. Refactoring a Reporting Services Report with Some SQL Magic
And congrats for the win. I often experience management kicking and screaming when I suggest similar optimizations.

I empathize with you about management kicking and screaming when you suggest optimizations. Why do you suppose that happens?

The biggest food distributor in xxxx (with some 90 "divisions"; 100,000+ service workers, and billions in sales), duplicates all the job streams and "data schemas" (VSAM files!) every time they create a new division ... which happens every few months.
The only change is the division "identifiers".
90+ duplicate job streams running every day.
The "head" responsible for this is a 30+ year "company" man.

When I saw mention of compiler support for ReadOnlyReferences in the C# 7.2 language, for passing variables by reference but without exposing data to modifications in a list of new features in version 4.7.2 of the Microsoft .NET Framework in What’s new in Microsoft .Net Framework 4.8, I realized that this is a big deal.
Here's why.
- Without this option, the only way to pass a read-only reference to an object is to create an adapter, so that you can pass through the properties through getter methods, omitting setters entirely.
- Writing such an adapter is time consuming and error-prone.
- Using the adapter adds a layer to every request to read a property on the underlying object, because the request must pass through the getter on the adapter, which passes it along to the getter on the adapted object.
- If your project has many of these, your source code tree has lots of branches that add little value, and the extra objects make the assembly bigger.
See C# Futures: Read-Only References and Structs for additional details not mentioned in the InfoWorld article, not the least of which is that this parameter modifier applies to structs, too. Presumably, that includes the system-defined structs, such as DateTime, char, and others.

If you're passing structs around as readonly references, you'll want to make sure the struct itself is readonly as well. The same applies if you're storing them in a readonly field. Otherwise, every time you access a property or method on the struct, the compiler will make a defensive copy to enforce the readonly-ness of the value.

That is precisely the point of the ReadOnlyReference modifier, which you would discover if you read that article all the way to the end.

Which one? The article from 2017, talking about the in modifier and readonly structs, which have already been released? Or the infoworld "subscriber only" article, which can't be read without signing up?

The article that you cited, about the in modifier is very explicit in it summary.

It also solves some sticky issues when you want to ensure that a method cannot modify contents of an object. It would have been a lot of work before to protect data in an object so that it could not be modified. You would have to basically deep clone it and use the clone.

Especially given that you may need only a subset of its methods and properties, it's often easier to create and adapter that exposes the needed methods as read only properties of itself, and forwards the required methods to the private instance which it adapts. It's usually straightforward to create a basic adapter to meet an immediate need, which can subsequently be extended to support more read only properties and/or forwarded methods.

If an adapter makes sense, then yes you can, but that may be a lot of adapters if there are many levels that need to be created for different objects, and if adapter does not make sense, them may be increasing maintenance significantly as need to provide different access to methods and properties.
|
|
|
|
|
All the better! If ReadOnlyReference enables you to dispense with multiple adapters, you are further ahead of the game in reducing code bloat. However, I usually prefer to extend an existing adapter over creating a new one, especially if the extension just adds a property. The exception to that rule is if that property is hidden to prevent information disclosure or leakage.

Why does PHP not have mutable constants?[^]
Uh...
(Found through WTDWTF)
What do you get when you cross a joke with a rhetorical question?
The metaphorical solid rear-end expulsions have impacted the metaphorical motorized bladed rotating air movement mechanism.
Do questions with multiple question marks annoy you???

The WTF for me was in the comments. It exists.[^] Just... why?

I wonder what problem somebody had that the only solution was to make constants mutable

I cry a little when I think of the years that I wasted on that language.

PHP and JavaScript are remarkably similar, especially in the ways that make both so malleable, at the cost of being dangerous in unskilled hands.
