ActiveSupport::Callbacks::Callback#make_lambda

Filters support:

  Symbols:: A method to call.
  Strings:: Some content to evaluate.
  Procs::   A proc to call with the object.
  Objects:: An object with a <tt>before_foo</tt> method on it to call.

All of these objects are compiled into methods and handled
the same after this point:

  Symbols:: Already methods.
  Strings:: class_eval'd into methods.
  Procs::   using define_method compiled into methods.
  Objects::
    a method is created that calls the before_foo method
    on the object.
