From: rick.hull@... Date: 2017-12-01T23:47:52+00:00 Subject: [ruby-core:84047] [Ruby trunk Feature#11547] remove top-level constant lookup Issue #11547 has been updated by RickHull (Rick Hull). Hm, this is surprising: ~~~ module Kernel X = 1 end String::X #=> 1 X = 2 String::X #=> NameError: uninitialized constant String::X ~~~ ---------------------------------------- Feature #11547: remove top-level constant lookup https://bugs.ruby-lang.org/issues/11547#change-68134 * Author: gucki1 (Corin Langosch) * Status: Closed * Priority: Normal * Assignee: * Target version: ---------------------------------------- If ruby cannot find a class in the specified scope it uses the top-level constant of the same name if it exists and emits a warning: ~~~ irb(main):006:0> class Auth; end => nil irb(main):007:0> class Twitter; end => nil irb(main):008:0> Twitter::Auth (irb):8: warning: toplevel constant Auth referenced by Twitter::Auth => Auth ~~~ In some cases this is not playing nicely with rails autoloading as can be seen here: https://github.com/rails/rails/issues/6931. Many more issues like this exist. Imo I don't see any reason why this fallback makes any sense. So I'd like to suggest to remove it completely or at least add an option to disable it. -- https://bugs.ruby-lang.org/ Unsubscribe:
