It has also been prposed that ".x" simply imply "self.x". An easier
notion would simply be:

  a.(strip!; upcase!)

This was discussed breifly on ruby-muse (suby-ruby mialing list). But
the conclusion was basically why bother when

  a = a.strip.upcase

works when speed is not an issue. And

  a.strip!; a.upcase!

works just as well when speed does matter.
