Module: Memoizable::Copy

Defined in:
lib/standard/facets/memoizable.rb

Overview

Include Memoizable alone with an #initialize_copy method that will copy the memoization cache when #dup or #clone is used.

TODO: Is this best approach? Perhaps a method to easily create the #initialize_copy method would suffice?
