[ruby-core:98678] [Ruby master Feature#16939] Alias _1 as _ for block numbered params

From: x3qt.dev@...
Date: 2020-06-08 15:38:20 UTC
List: ruby-core #98678
Issue #16939 has been reported by x3qt (Yury Polyakov).

----------------------------------------
Feature #16939: Alias _1 as _ for block numbered params
https://bugs.ruby-lang.org/issues/16939

* Author: x3qt (Yury Polyakov)
* Status: Open
* Priority: Normal
----------------------------------------
I propose to alias `_1` as `_` for block numbered params, so the following statements should be equal –
``` ruby
[1,2,3].map { _1 ** 2 }

[1,2,3].map { _ ** 2 }
```
There is an [anonymous function argument literal](https://clojure.org/reference/reader#_dispatch) in Clojure and it feels natural all the way, hope we can have the one too.
