I just wanted to add: there are many bad implementations in ruby.  In 
addition, there are many bad programmers that badly implement 
ruby--check out just about any thread on this forum.  A lot of 
solutions(most?) will string together 3 or 4 ruby method calls in a one 
liner with a couple of regex's sprinkled in for good measure.  As far as 
I can tell, not many people know how to write clear efficient ruby code. 
Of course their battle cry is: ruby is so inefficient anyway, what does 
it matter if I write inefficient and obfuscated code.
