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

  # 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.
