Feature #17140: Merge Enumerable#grep(_v) with Enumerable#select/reject
https://bugs.ruby-lang.org/issues/17140
* Author: baweaver (Brandon Weaver)
* Status: Open
* Priority: Normal
----------------------------------------
In recent versions of Ruby we've gotten new behavior of some Enumerable methods like any?, all?, none?, one?, and others to support a single argument pattern that responds to `===`. This is very powerful, and very useful.
Currently Enumerable has `grep` and `grep_v` which allow this as a way to filter lists.
These names require some understanding of Unix to be familiar with, but naming aside, I feel it may make sense to implement `===` pattern arguments in `Enumerable#select` and `Enumerable#reject` as with the above.
Proposed Syntax:
```ruby
list_of_numbers.select(1..10)
words.reject({ 'and', 'the', 'of' })
```
I believe this would help with readability and would simplify syntax options by unifying on this standard.
My concern is that `Enumerable#find` already takes a single argument, `ifnone`, and may not be able to implement this behavior. I would be curious to see how many use `ifnone` but feel this would be more critically breaking to do.
