Question: I was having a discussion with some programmer friends who said that they see Ruby programmers (in particular) producing a lot of code that's "too clever". So I'm wondering what would that look like? I'm referring to the unnecessary use of an obscure language feature in a context in which something straightforward would have worked just as well or better. Know any good Ruby examples of this?

Answer: 
I'm not sure if this qualifies as "too clever," but I have seen code that made me wonder if the author was either a genius or an idiot. One developer seemed to have a rule that no method should have more than two lines of code. That pushed the call stack very deep and made debugging rather difficult. The upside is that his overall design was very abstract and even elegant from a distance.
method\_missing can be abused and it's one of those things that may cause you to pull your hair out when you have to fix a bug 3 months after you've written code.
