=begin
Clever! Though I don't think that would parse the way you want. This would work though, obviously:

  enumerable class Foo ...

=end

Feature #8839: Class and module should return the class or module that was opened

With the change for https://bugs.ruby-lang.org/issues/3753, "def" forms now return the symbolic name of the method defined. Because class and module bodies just return the last expression in their bodies, this means they will now usually end up returning a symbol for the last method defined. This does not seem useful or correct.

I think class and module should return a reference to the class or module just opened. This would make the return value useful and consistent.
