Subject: module_functions are private?

I have a piece of code that does something like this:

  module M
    def foo; end
    module_function :foo
  end

  class Foo
    include M
  end

  Foo.new.foo()

and was very surprised to discover that it doesn't work:

  NameError: private method `foo' called for #<Foo:0x402db40c>
          from (irb):10

Why does module_function() make foo() private?
