> I don't think annonymous functions have anything special to do with FP or OO for that matter. Maybe someone can fill in on this?

Anonymous functions are of no use until functions are first-class citizens (otherwise, there's no way to call them!), and this has always been the case in FP languages.

I do agree though that the focus on mathematical "purity" is a much more defining characteristic of FP.

Closures were an integral part of Smalltalk's design.

And functions as first class citizens is not a particularly high bar. I mean, C has higher order functions.

I'm excited to use higher-order functions in C someday :)

[rbehrends]

You can do that now. Higher-order functions are simply functions that can take other functions as parameters or return them as results. C has been able to do that since forever. It's not something fancy: pretty much every programming language has something along these lines.

What is rarer is closures, but that's a different concept. You can have higher-order functions without having closures.

Haha - I'm simply stating that I'm excited to do it and not for it to be possible :P

C# & Java has anonymous functions, but not 1st-class functions AFAIK

EDIT: but then again, they truely are of no use :P hehe
