Hhmmm... I might agree with you if we were trying to advocate Perl.  But
one of the selling points of Ruby is its clarity.  I'd rather show how you
can perform tasks with more clarity and ease than in other languages.

I particularly liked:

a, b = b, a   # Who needs tmp variables?

def twice; yield; yield; end
twice {print "Hello World"}

A sig can be something like:

a, b = b, a   # Who needs tmp variables?
