Subject: [ruby-core:51282] [ruby-trunk - Bug #7662][Assigned] Unable to define a method with bare `**`


Issue #7662 has been updated by mame (Yusuke Endoh).

Status changed from Open to Assigned

Thanks for your feedback.  I'm neutral for bare `**` itself.
But it is too late a bit to discuss the spec and there is an obvious workaround:

  def foo(**dummy)
  end

Of course, we can add bare `**' later (say, in 2.0.1).


BTW:

> I use bare `*` often in combination with bare `super` to extend a superclass without being brittle to its exact signature.

I don't think that it is a good idea to ignore arguments silently just for a bare `super`.
You should call super with explicit argument delegation if your overriding method changes the signature of its parent method.

This works:

  def foo(*)
  end

This does not:

  def foo(**)
  end

This does not:

  def foo(*, **)
  end

I use bare `*` often in combination with bare `super` to extend a superclass without being brittle to its exact signature. With keyword arguments, this seems like it will be impossible. I am opening several other related issues.
