The if ... then ... else ... end statements people have been posting  
are perfectly legal Ruby.  Fire up irb an give them a spin.  It's  
basically just collapsing an if statement to one line, then capturing  
the proper return (since statements return things in Ruby).  The  
"then" is just a pretty replacement for the ; here.

Hope that helps.
