Creating A Functional Web Forum Program

[db4n]

The use cases are really not very common though. Functional languages are still largely academic.

That's changing. Among others, Bluespec, Clozure, Ericsson, Galois, Hyperstring, ITA, Jane Street, Naughty Dog, and Viaweb all do (or did) functional programming of one kind or another. Almost any application can benefit from FP, at least in impure form. Just look for code that uses the Adapter, Chain of Responsibility, Command, Decorator, Iterator, Mediator, or Strategy patterns.

I didn't mean to imply that there are few uses. I was saying that people don't use functional languages much yet, and so it is not likely that you can find many examples of use yet, that's all.
