Ruby equivalent to Python's getattr

I was looking for the Ruby equivalent to getattr and I ran into this article:

http://stackoverflow.com/questions/786412/what-is-the-ruby-equivalent-of-pythons-getattr

The answer was not generic enough for me. I'd like to implement a Ruby equivalent to Python's built-in sorted function.

So after a little more searching, I found the answer: send and posted it.
