From: shevegen@... Date: 2018-05-08T20:42:11+00:00 Subject: [ruby-core:86950] [Ruby trunk Bug#14744] Refinements modules have a superclass Issue #14744 has been updated by shevegen (Robert A. Heiler). > I thought modules can never have a superclass in Ruby. This may be a bug, I think; other modules do not seem to have anything but themselves if you call .ancestors() on them either. ---------------------------------------- Bug #14744: Refinements modules have a superclass https://bugs.ruby-lang.org/issues/14744#change-71915 * Author: Eregon (Benoit Daloze) * Status: Open * Priority: Normal * Assignee: * Target version: * ruby -v: ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux] * Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN ---------------------------------------- ~~~ $ ruby -e 'module M; refine Array do; p self; p self.class; p ancestors; end; end' #<refinement:Array@M> Module [#<refinement:Array@M>, Array, Enumerable, Object, Kernel, BasicObject] ~~~ So the refinement module (self in the `refine Array do` block) is a Module, but looking at its ancestors it has Array as a "superclass". Is that expected? I thought modules can never have a superclass in Ruby. -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
