Issue #9887 has been updated by Nobuyoshi Nakada. Duplicates Feature #8967: add uninclude and unextend method added ---------------------------------------- Feature #9887: Add uninclude please https://bugs.ruby-lang.org/issues/9887#change-46989 * Author: Robert A. Heiler * Status: Open * Priority: Low * Assignee: * Category: * Target version: ---------------------------------------- Hi! I would like to have a way to cleanly uninclude a module. Consider: ```ruby module Foo TEST = '123' end class Bar include Foo end ``` Now I would like to uninclude Foo. I can remove constants and methods already, i.e. via `remove_method` or `undef`* and constants can be removed as well but I would like to have something like: ~~~ruby class Bar uninclude Foo end ~~~ or ~~~ruby Bar.uninclude Foo Bar.remove_ancestors Foo ~~~ Would this be possible? It might be useful but perhaps there is a reason why this can not be added. -- https://bugs.ruby-lang.org/
