Subject: [ruby-core:97333] [Ruby master Feature#16667] Allow parameters to Symbol#to_proc and Method#to_proc

Issue #16667 has been updated by Hanmac (Hans Mackowiak).


i tried `ary.map.with_object(:id,&:dig)` but it just returned `:id`

but this one would work: `ary.each_with_object(:id).map(&:dig)`

----------------------------------------
Feature #16667: Allow parameters to Symbol#to_proc and Method#to_proc
https://bugs.ruby-lang.org/issues/16667#change-84455

* Author: jgomo3 (Jes�s G�mez)
* Status: Open
* Priority: Normal
----------------------------------------
Allow parameters to Symbol#to_proc and Method#to_proc

So we can say:

``` ruby
ary.map(:dig.to_proc(:id))
```


Instead of

``` ruby
ary.map { |e| e.dig(:id) }
```


Oppening the posibilities to refine the `&` operator in the future, for something like:


``` ruby
ary.map(&(:dig, :id))
```
