In my experience, functional programming really shines in rapid prototyping. However, in production code I would try to avoid it, because it can confuse developers that are not used to it and also sometimes I struggle myself when decoding the short "clever" one-liner that I wrote 5 years ago. But if you want to write very powerful code withing a single line it is really great and makes you very productive for finding solutions fast. It is a bit like the Perl throw-away code we were writing in the 1990s. ;-) just my 2 ct
