Subject: no singleton methods for Fixnums?

Hello,

I ran across the following and was just curious as to why this doesn't work?
(Just in case you're wondering why I'm asking all of these super-obscure
questions, I'm giving a presentation at our RUG tonight, and I just wanted
to make sure I knew... well, everything.)

  irb(main):002:0> x = 5
  => 5
  irb(main):003:0> def x.foo; 'foo'; end
  TypeError: can't define singleton method "foo" for Fixnum
          from (irb):3


So what am I doing wrong?

Chris
