 I'm seeing different behaviour when including a module into Class in
 MacRuby vs Ruby 1.9.2. This is a simplification of a problem I'm seeing
 running Mocha [1] tests in MacRuby. I seems to be specific to including
 the module into the Class class and not a user-defined class. It also
 doesn't seem to matter whether the class has already been defined or not.

 {{{
 $ rvm macruby
 $ irb
 macruby-0.6 > module X; def x; "x"; end; end
  => nil
 macruby-0.6 > class Class; include X; end
  => Class
 macruby-0.6 > Class.new.x
 NoMethodError: undefined method `x' for #<Class:0x20020f960>
         from /Users/jamesmead/Code/mocha/(irb):3:in `<main>'
 }}}

 {{{
 $ rvm 1.9.2
 $ irb
 ruby-1.9.2-preview1 > module X; def x; "x"; end; end
  => nil
 ruby-1.9.2-preview1 > class Class; include X; end
  => Class
 ruby-1.9.2-preview1 > Class.new.x
  => "x"
 }}}

 {{{
 $ rvm macruby
 $ irb
 macruby-0.6 > module X; def x; "x"; end; end
  => nil
 macruby-0.6 > class Y; include X; end
  => Y
 macruby-0.6 > Y.new.x
  => "x"
 }}}

 {{{
 $ rvm macruby
 $ irb
 macruby-0.6 > module X; def x; "x"; end; end
  => nil
 macruby-0.6 > class Y; end
  => nil
 macruby-0.6 > class Y; include X; end
  => Y
 macruby-0.6 > Y.new.x
  => "x"
 }}}
