Feature #19134: ** is not allowed in def foo(...)
https://bugs.ruby-lang.org/issues/19134#change-100293

* Author: shugo (Shugo Maeda)
* Status: Open
* Priority: Normal
* Assignee: matz (Yukihiro Matsumoto)
----------------------------------------
`*` and `&` are allowed in the body of a method with `...` argument forwarding, but `**` is not allowed.

```
def foo(...)
  bar(*) # OK
  baz(&) # OK
  quux(**) # NG
end
```

Is it intended behavior?

It seems that parse.y has code like `#ifdef RUBY3_KEYWORDS`, and if RUBY3_KEYWORDS, `**` will also be supported.
