Subject: [ruby-core:95340] [Ruby master Feature#16253] Shorthand "forward everything" syntax
Date: Tue, 15 Oct 2019 15:53:01 +0000 (UTC)	[thread overview]
Message-ID: <redmine.journal-82049.20191015155300.73742571f7b6a68f@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-16253.20191015153838@ruby-lang.org

Issue #16253 has been updated by Eregon (Benoit Daloze).


`...` has been proposed a few times as well, I'm not sure if there is a ticket for it:

```ruby
  def foo(...)
    @bar.foo(...)
```

Feature #16253: Shorthand "forward everything" syntax
https://bugs.ruby-lang.org/issues/16253#change-82049

* Author: Dan0042 (Daniel DeLorme)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
----------------------------------------
What about using this:

```ruby
  def foo(*)
    @bar.foo(*)
```

to mean this:

```ruby
  def foo(*a, **o, &b)
    @bar.foo(*a, **o, &b)
```

I used `def foo(*)` because that's currently valid ruby code, but I'm fine with any syntax.

It's like the no-parentheses `super` shorthand, but for any method.

It makes it easier to write correct forwarding code. 

If rubyists must be told they have to change their forwarding code in 2.7 (due to keyword arguments), the pill might be easier to swallow if the change is a reduction rather than an increase in verbosity.

And we'd even be future-proof if an eventual FOURTH kind of parameter is introduced!!!!
