Subject: Re: Alias for Module Method

Hey,

Yeah, in your code Ruby tries to alias an instance method called :func
defined in the module. Since it doesn't exist, it doesn't work. Alias 
and alias_method only work on instance methods, but luckily singleton 
methods like :func in your example are really instance methods defined 
in the singleton class of MyModule.

module MyModule
  def MyModule.func
    puts 'Hello'
  end

  class << self # or, class << MyModule
    alias funcAlias func
  end
end

MyModule.funcAlias

Take care,

-Luke
