Issue #21916 has been updated by Eregon (Benoit Daloze). * [Feature #21962] Add deep_freeze for recursive freezing (eregon) * A revised proposal that aims to address the previous discussion. * It follows the behavior of `Ractor.make_shareable`, and is also consistent with `IceNine.deep_freeze`, so the semantics are already well understood and have existing usage. * Is `Kernel#deep_freeze` OK? It seems the obvious fit, given `Kernel#freeze`. * Semantics are are OK? * I can implement it. ---------------------------------------- Misc #21916: DevMeeting before RubyKaigi 2026 https://bugs.ruby-lang.org/issues/21916#change-116835 * Author: ko1 (Koichi Sasada) * Status: Open ---------------------------------------- RubyKaigi 2026 will be at Hakodate, Japan, Apr 22th - 24th.
