Issue #16378 has been updated by jeremyevans0 (Jeremy Evans). Eregon (Benoit Daloze) wrote in #note-10: > @jeremyevans0 or @nobu Could you implement it on `master`? I've implemented basic support, which passes make check: https://github.com/jeremyevans/ruby/commit/672901facca6f88ae40b4ea8ef59ef04efd5a5de I think ripper support is probably broken for it, and the idFWD_KWREST sections (not currently enabled) are probably also wrong. @nobu, could you please fix the ripper support and idFWD_KWREST sections? ---------------------------------------- Feature #16378: Support leading arguments together with ... https://bugs.ruby-lang.org/issues/16378#change-85857 * Author: Eregon (Benoit Daloze) * Status: Open * Priority: Normal * Assignee: matz (Yukihiro Matsumoto) * Target version: 3.0 ---------------------------------------- I think this is very important, otherwise `...` can be used only very rarely. For instance, `method_missing` typically want to access the method name like: ```ruby def method_missing(name, ...) if name.to_s.end_with?('?') self[name] else fallback(name, ...) end end ``` See the original feature: https://bugs.ruby-lang.org/issues/16253#note-19. I think most people expect `def method_missing(name, ...)` to work. -- https://bugs.ruby-lang.org/ Unsubscribe:
