module RuboCop
module Cop
module Lint
# Checks if `include` or `prepend` is called in `refine` block.
# These methods are deprecated and should be replaced with `Refinement#import_methods`.
#
# It emulates deprecation warnings in Ruby 3.1.
#
# @safety
# This cop's autocorrection is unsafe because `include M` will affect the included class
# if any changes are made to module `M`.
# On the other hand, `import_methods M` uses a snapshot of method definitions,
# thus it will not be affected if module `M` changes.
#
# @example
#
# # bad
# refine Foo do
# include Bar
# end
#
# # bad
# refine Foo do
# prepend Bar
# end
#
# # good
# refine Foo do
# import_methods Bar
# end
