I think if Matz wanted this in Ruby, it would be there by now :-)  The
thing is, if you have:

   x = 0
   x++

to increment x here would mean to increment the object, namely 0,
which you can't do.  (See earlier discussions for more on this.)

That's certainly true: in Ruby you don't have to do nearly as much
explicit incrementing as in other languages.
