Subject: [ruby-core:100382] [Ruby master Feature#17260] Promote pattern matching to official feature
Date: Mon, 12 Oct 2020 07:45:54 +0000 (UTC)	[thread overview]
Message-ID: <redmine.journal-87994.20201012074553.3007@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-17260.20201011120315.3007@ruby-lang.org

Issue #17260 has been updated by nobu (Nobuyoshi Nakada).


It disallows assignments to other than local variables.

https://github.com/nobu/ruby/runs/1240626799#step:15:315
```
SyntaxError: (eval):1: syntax error, unexpected instance variable
def self.inc(x) = x + 1 => @x
                           ^~
```


----------------------------------------
Feature #17260: Promote pattern matching to official feature
https://bugs.ruby-lang.org/issues/17260#change-87994

* Author: ktsj (Kazuki Tsujimoto)
* Status: Open
* Priority: Normal
* Target version: 3.0
----------------------------------------
I propose to promote pattern matching to official feature.

The current specification is basically fine, but I'd like to reconsider single line pattern matching (`expr in pat`) and suggest removing it once in 3.0.
