To make a minor point, I see this use of module_function often, even in 
the standard library.  I don't like it.

In addition to the module_function method, there's the module_function 
scoping state, like public or private or protected, which is likewise 
enabled by calling module_function without arguments.  Therefore we can 
make a D.R.Y. equivalent:

module Test
  module_function

  def foo
    puts "Foo"
  end
end
