Subject: [ruby-core:117502] [Ruby master Bug#20423] Anonymous block forwarding shouldn't work with ... but it does
Date: Fri, 12 Apr 2024 07:30:07 +0000 (UTC) [thread overview]
Message-ID: <redmine.journal-107889.20240412073007.73@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-20423.20240411183953.73@ruby-lang.org
Issue #20423 has been updated by nobu (Nobuyoshi Nakada).
https://github.com/ruby/ruby/pull/10514
----------------------------------------
Bug #20423: Anonymous block forwarding shouldn't work with ... but it does
https://bugs.ruby-lang.org/issues/20423#change-107889
* Author: tenderlovemaking (Aaron Patterson)
* Status: Open
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
According to [this note](https://bugs.ruby-lang.org/issues/11256#note-16), anonymous block forwarding should only be supported when explicitly used in the method signature.
For example:
```ruby
def foo(&) = bar(&) # OK
def foo = bar(&) # NG
```
However, if you use `...` in the method signature, `&` seems to work:
```ruby
def foo(...)
# bar(*) # Syntax Error
# bar(**) # Syntax Error
bar(&) # not a syntax error, but I think it should be
end
```
I think this should be a syntax error.
