Is there a reason why this doesn't work with keyword arguments too?

For example: ``` def foo(bar:, ...) other(...) end ```

results in syntax error

Keyword arguments are not leading arguments. Trying to support what you want was not in scope. I think trying to support what you want would significantly increase the complexity, especially if you wanted to support `def foo(arg, kwarg: , ...)` as well. You should use: ```ruby def foo(*, bar:, **, &) other(*, **, &) end ``` ---------------------------------------- Feature #16378: Support leading arguments together with ... https://bugs.ruby-lang.org/issues/16378#change-109626 * Author: Eregon (Benoit Daloze) * Status: Closed * 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. ---Files-------------------------------- ruby_2_7_lead_args_forwarding.patch (8.98 KB) -- https://bugs.ruby-lang.org/
