Subject: module_function semantics

Hi all!

I'm trying to understand some code in the stdlib (drb/drb.rb, to be
particular).

Is there any difference between:

  module Foo

    module_function
    def bar()
      "baz"
    end

  end

and

  module Foo

    def Foo.bar()
      "baz"
    end
  end

?

Am I right in guessing that the former gives both a module and a mixin
function of the same name, whereas the latter gives on a module function?
Or are they in fact identical?

William
