[ruby-core:84150] [Ruby trunk Feature#11286][Closed] [PATCH] Add case equality arity to Enumerable's sequence predicates.
From:
ruby-core@...

ruby-core #84150
Issue #11286 has been updated by marcandre (Marc-Andre Lafortune).
Status changed from Open to Closed
Target version set to 2.5
Thank you Matz
D.E. Akers: thanks for the patch! I adapted it for better handling of enumerables yielding multiple arguments, and also changing Hash#any? / Array#any? which have their own versions.
Merged.

Feature #11286: [PATCH] Add case equality arity to Enumerable's sequence predicates.
https://bugs.ruby-lang.org/issues/11286#change-68254
* Author: 0x0dea (D.E. Akers)
* Status: Closed
* Priority: Normal
* Assignee: matz (Yukihiro Matsumoto)
* Target version: 2.5
----------------------------------------
## Proposal
It is proposed that `Enumerable`'s sequence predicates (`#all?`, `#any?`, `#none?`, and `#one?`) be augmented to return, in the case of a single argument, whether their query holds when each element is supplied to the argument's `#===` method.
## Rationale
`Enumerable#grep` filters by case equality, allowing us to write very natural and expressive code:
```ruby
strs.select { |str| /foo/ === str }
strs.grep(/foo/)
nums.select { |num| (5..10) === num }
nums.grep(5..10)
```
In addition to taking advantage of the versatility of case equality, it lets us do away with the syntactic noise incurred by opening a block. `#grep` is a very nice method! Let's make `#all?` and friends more like `#grep`.
