Subject: [ruby-dev:51196] [Ruby master Bug#19132] `**` を引数に指定すると no anonymous keyword rest parameter になる
Date: Wed, 16 Nov 2022 05:15:21 +0000 (UTC)	[thread overview]
Message-ID: <redmine.issue-19132.20221116051519.82@ruby-lang.org> (raw)
In-Reply-To: <redmine.issue-19132.20221116051519.82@ruby-lang.org>

Issue #19132 has been reported by tommy (Masahiro Tomita).

----------------------------------------
Bug #19132: `**` を引数に指定すると no anonymous keyword rest parameter になる
https://bugs.ruby-lang.org/issues/19132

* Author: tommy (Masahiro Tomita)
* Status: Open
* Priority: Normal
* ruby -v: ruby 3.2.0preview3 (2022-11-14) [arm64-darwin21]
* Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
Ruby 3.2.0-preview3 で次のスクリプトを実行するとエラーになります。
```ruby
def hoge(a, *, k: nil, **)
  foo(*, **)
end
```

```
% ruby hoge.rb   
hoge.rb:2: no anonymous keyword rest parameter
```

次のようにキーワードパラメータが `**` だけであればエラーになりませんでした。
```ruby
def hoge(a, *, **)
  foo(*, **)
end
```
