Subject: [ruby-core:123150] [Ruby Bug#18878] parse.y: Foo::Bar {} is inconsistently rejected
Date: Mon, 01 Sep 2025 01:44:49 +0000 (UTC) [thread overview]
Message-ID: <redmine.journal-114482.20250901014449.31364@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-18878.20220626130635.31364@ruby-lang.org
Issue #18878 has been updated by yui-knk (Kaneko Yuichiro).
Patch:
* Support only `Foo::Bar {} + 1`: https://github.com/yui-knk/ruby/tree/bug_18878_2
* Support both `Foo::Bar {} + 1` and `Foo::Bar do end` (and `Foo::Bar do end + 1`): https://github.com/yui-knk/ruby/tree/bug_18878
----------------------------------------
Bug #18878: parse.y: Foo::Bar {} is inconsistently rejected
https://bugs.ruby-lang.org/issues/18878#change-114482
* Author: qnighy (Masaki Hara)
* Status: Assigned
* Assignee: ydah (Yudai Takada)
* ruby -v: ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x86_64-linux]
* Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
The following source doesn't parse:
```ruby
Foo::Bar {}
```
despite the following:
```ruby
bar # local variable or method call
Bar # constant
bar() # method call
Bar() # method call
bar {} # method call
Bar {} # method call
bar() {} # method call
Bar() {} # method call
Foo::bar # method call
Foo::Bar # constant
Foo::bar() # method call
Foo::Bar() # method call
Foo::bar {} # method call
# Foo::Bar {} # SyntaxError
Foo::bar() {} # method call
Foo::Bar() {} # method call
```
Especially considering `Bar {}`, this looks like a missing implementation rather than an intentional behavior.
