[ruby-core:101757] [Ruby master Feature#16378] Support leading arguments together with ...

Issue #16378 has been updated by Dan0042 (Daniel DeLorme).


@nagachika I would really like to see this backported to 2.7 ... may I ask for the status?

----------------------------------------
Feature #16378: Support leading arguments together with ...
https://bugs.ruby-lang.org/issues/16378#change-89584

* Author: Eregon (Benoit Daloze)
* Status: Closed
* 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.
