Anyone here use Ruby much? What, besides Ruby on Rails, are its advantages over Python, PHP, Perl, etc? I'm eager to learn Ruby on Rails for some fast web apps development, but beyond that I don't see much of an advantage for normal scripting. I tried to convert a very small script (only a few lines) that simply parses out some text via regex from the stdin, but the Ruby verion was slower (using a simple 1 liner and code blocks). Thoughts?
