It can't be called directly. Another note, you can't pass methods directly just like a one can do in Python or Javascript and then call it directly. The maximum u can do is to pass the name(symbol or string) and call it via send or eval methods, Or pass method object and call it from there. Anyway check this <a href="http://www.khelll.com/blog/ruby/ruby-dynamic-method-calling/" rel="nofollow">post</a> on dynamic method invocation in Ruby. @billy, cause mix is a Symbol there.

In other words, it should be fired after loading a class, any idea? Keep it up! Great post! :)
