I have updated my fix for [Bug #15620] to also issue a warning in cases it returns the argument it receives without modification. Since both 2.5.x and 2.6.x has [Bug #15620], there may be code in the wild that depend on the unintended lambda conversion behavior. It might make sense to put the 2.4.x behavior back for 2.7.0-preview2 to find out whether it's an issue. https://github.com/ruby/ruby/pull/2289 ---------------------------------------- Feature #15973: Let Kernel#lambda always return a lambda https://bugs.ruby-lang.org/issues/15973#change-81779 * Author: alanwu (Alan Wu) * Status: Assigned * Priority: Normal * Assignee: matz (Yukihiro Matsumoto) * Target version: ---------------------------------------- When Kernel#lambda receives a Proc that is not a lambda, it returns it without modification. l propose to change `Kernel#lambda` so it always returns a lambda. Calling a method called lambda and having it do nothing in effect is not very intuitive. https://github.com/ruby/ruby/pull/2262 Judging from marcandre's investigation here: https://bugs.ruby-lang.org/issues/15620#note-1, changing the behavior should not cause much breakage, if any. This also happens to fix [Bug #15620] -- https://bugs.ruby-lang.org/ Unsubscribe:
