I realize this is a contrived example on your part, but you did  
choose it and were trying to make a relevant point. That said, I have  
yet to see an example of returning used in a non-contrived way.

   def foo(a)
     a.map { |x| x }
   end

More readable, faster, better... once again returning is used in a  
completely useless way...
