Yeah, but give me a language (e.g. - Perl, etc) that lets me make closures, instead of anonymous inner classes that implement an interface with exactly one method, any day. Fascist OOP can lead to some real code bloat, and I suspect that is starting to dawn on the leadership of this industry. A bit tangential, but it's something I am reminded of day in and out trudging through Java code at work, and one of the "quick payback" reasons I'd like any new guy to understand FP. (oh, and Python and JavaScript are, at least in a "compatible style", functional programming languages)
