Interesting -- this is another difference between module_function 
without arguments and extend self:

module A3
   extend self
   def f; g; end
   private
   def g; "A3.g"; end
end

A3.g # raises NoMethodError: private method `g' called for A3:Module
A3.f # => "A3.g"

I think the behavior of extend self is more appropriate than the 
module_function one.
