Subject: [ruby-changes:66290] 636d4f7eb9 (master): Avoid setting the visibility of refinement method entries
https://git.ruby-lang.org/ruby.git/commit/?id=636d4f7eb9 From 636d4f7eb9f3fcb088e1a44af4181c4aa36789b4 Mon Sep 17 00:00:00 2001 From: Alan Wu <XrXr@u...> Date: Thu, 20 May 2021 18:52:32 -0400 Subject: Avoid setting the visibility of refinement method entries Since refinement search is always performed, these entries should always be public. The method entry that the refinement search returns decides the visibility.
