[ruby-core:115222] [Ruby master Bug#19983] Nested * seems incorrect

Issue #19983 has been updated by Eregon (Benoit Daloze).


Agreed, I think supporting `*` fully for blocks would be a good way to solve this.
If that's deemed not desirable, then I think such code should be SyntaxError to avoid confusion and make it clear what works and does not.

Bug #19983: Nested  * seems incorrect
https://bugs.ruby-lang.org/issues/19983#change-105139

* Author: Eregon (Benoit Daloze)
* Status: Open
* Priority: Normal
* ruby -v: ruby 3.3.0dev (2023-10-30T09:27:06Z master 14fa5e39d7) [x86_64-linux]
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 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.
