Subject: [ruby-core:116177] [Ruby master Bug#19983] Nested  `*` seems incorrect

Issue #19983 has been updated by jeremyevans0 (Jeremy Evans).

Status changed from Open to Closed

This was fixed in Ruby 3.3:

```
$ ruby -v -e 'def m(*); ->(*) { p(*) }; end; m(1).call(2)'
ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [x86_64-openbsd]
-e:1: anonymous rest parameter is also used within block
-e: compile error (SyntaxError)
```

Bug #19983: Nested  `*` seems incorrect
https://bugs.ruby-lang.org/issues/19983#change-106192

* Author: Eregon (Benoit Daloze)
* Status: Closed
* Priority: Normal
* ruby -v: ruby 3.3.0dev (2023-10-30T09:27:06Z master 14fa5e39d7) [x86_64-linux]
* Backport: 3.0: DONTNEED, 3.1: DONTNEED, 3.2: UNKNOWN
----------------------------------------
```
$ ruby -v -e 'def m(*); ->(*) { p(*) }; end; m(1).call(2)'  
ruby 3.3.0dev (2023-10-30T09:27:06Z master 14fa5e39d7) [x86_64-linux]
1
```

But I would expect `2`.

Much like:
```
$ ruby -e 'def m(a); ->(a) { p(a) }; end; m(1).call(2)'
ruby 3.3.0dev (2023-10-30T09:27:06Z master 14fa5e39d7) [x86_64-linux]
2
```

i.e. the inner variable should win.

Also affects at least 3.2.
