Don't.  That's a pretty traditional rite of passage :-)

Interesting.  The mind boggles at the side-effect and hard-to-find bug
possibilities :-)  But it's quite cool, and I'd never known of it
before.

   class E
     include Enumerable
     def each
       3.times {|i| puts "Hello!"; yield i }
     end
   end

   def x(*args)
     p *args
   end

   x(*E.new)
