# 
# Refinement is a class of the `self` (current context) inside `refine`
# statement. It allows to import methods from other modules, see
# #import_methods.
#
class Refinement < Module
  private

# 
  # Imports methods from modules. Unlike Module#include, Refinement#import_methods
  # copies methods and adds them into the refinement, so the refinement is
  # activated in the imported methods.
  #
  # Note that due to method copying, only methods defined in Ruby code can be
  # imported.
  #
  #     module StrUtils
  #       def indent(level)
  #         ' ' * level + self
  #       end
  #     end
  #
  #     module M
  #       refine String do
  #         import_methods StrUtils
  #       end
  #     end
  #
  #     using M
  #     "foo".indent(3)
  #     #=> "   foo"
  #
  #     module M
  #       refine String do
  #         import_methods Enumerable
  #         # Can't import method which is not defined with Ruby code: Enumerable#drop
  #       end
