Who's yet to open the book on this?
This is one such topics where the whole world starts doing something about, but I keep it safe in my todo list.
Just a quick question from the dummies perspective.
1. Will functional programming make all the OOAD concepts obsolete or it can get along well with OOAD?
2. What's your take? You like it?

for mine it's something everyone talks about as the new sliced bread,
and later all but disappears into some niche, like lisp or prolog, or even forth.

Hey, forth had its place  . I had gainful employment for over a year working in forth for the Anchorage AK International airport on their vehicle gate security systems. Forth did what it was originally designed for (device and instrument control) reasonably well.

Was Forth a fourth generation language?
Can you imagine interpreting a job requirement that says what is needed is, "Go, Forth and Javascript".
- I would love to change the world, but they won’t give me the source code.

Actually, Forth did what it was designed for reasonably well.
Unlike MUMPS, which was developed by (hold your breath) doctors! And the VA STILL uses it. One of the only 'languages' that allowed you write a complete program in a string variable (using user input) and execute it immediately. One nice thing was there were only 25 reserved words, each one starting with a different letter (Z was for anything that did not fit) and a program was allowed use just the first letter for the reserved word.

MUMPS is an old, procedural language and I was not thrilled to have to learn it in 2001. However, the database Cache is BLAZING fast and works very well for storing Medical data. Fortunately, I no longer have to code MUMPS, but I still respect the speed.

Forth was supposed to be a fourth generation programming language but the computer that it was developed on would only allow 5 character file names.

I did a large project in Forth back in the '80s. Never again.
Forth is a write only language

Not if you do proper decomposition and give your words readable names. I worked in forth for many years and my old code is still very readable today. Also, good commenting helps!

I've heard the "write-only" complaint about Perl and APL, too ...
I've seen horrible Perl; but also have seen huge Perl apps that were a cakewalk to understand.
APL worked very well at giving you the whole algorithm in a concise picture.
Ask Morgan-Stanley how "K works, for people who are under serious coding pressure.
I'd say it's a matter of developer community and praxis, without which every language can be a bomb.
Language (syntax) requirements never prevent all the bad things you can do.

1. As matter of fact, OOAD concepts and functional programming are both dated. Lately there's some interest in the features of functional programming, that's true.
2. I like it but I don't fully understand it. That is often I am not able to see how my job would be easier using functional programming.

Some eggheads pretend to understand it and insist that the benefits outweigh any inconveniences. Never do they say anything about the downsides or, god forbid, admit that they have no clue.
I have lived with several Zen masters - all of them were cats.
His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.

I do Functional2 programming. Not only do I write functions but they also function.

But do they do the function for which they were designed? There has to be a set procedure, and some method in your madness.

Functional programming is loved mainly by eggheads, like my boss who has a degree in mathmatics. He also loves VB, so take that as a reference however you like.
Long ago, I was tortured with LITHP and Scheme by egghead professors. Twice. That's enough for the rest of my life and I can easily live with not ever having to see that stuff again. Maybe aliens from Ceti Alpha love it, but I also suspect it's the reason why Ceti Alpha Six exploded.

Quote: degree in mathmatics. He also loves VB
That's OK. Mathmaticians, Madmaticians can actually love VB. On the other hand, proper Mathematicians can only distaste it.

So you say that there are several distinct sorts of eggheads?

I see you don't like mathematics people.

Nah, I just don't want to be assimilated and become an egghead myself.

I'm sure Star Fleet used Functional Programming and that's why they thought Ceti Alpha Five was Six.

I'm a Programmer, I use functions in my code all the time. Tada!

Functional programming preceeded OOP. OOP is (I think) a better idea.
Turbo Pascal started out as a functional language.
Fortran is a fucntional lanugage.
C is a functional language.
Javascript is not functional, but it is a functional language.
Visual Basic was a functional language.
My problem with the sudden interest (by people who don't matter) in functional programming is that everyone thinks OOP should be abandoned, or that functional crap should be injected into the OOP paradigm. These people are, for lack of a better term, retards.
