11:18 AM Ruby Feature #15831: Add `Array#extract`, `Hash#extract`, and `ENV.extract`

I'm wondering to know whether use-cases, mentioned in https://bugs.ruby-lang.org/issues/15831#note-9, are good enough to reconsider the decision to add these methods to Ruby? bogdanvlviv (Bogdan Denkovych)

Hello.
I might have missed something, but examples like:

elsif

> I also concern about the name conflict with the ActiveSupport method.
I guess this comment addressed https://bugs.ruby-lang.org/issues/15863 that adds `Hash#slice!`, right?
Active Support doesn't have any `extract` methods, only `e... bogdanvlviv (Bogdan Denkovych)

> Let me see the real-world use-case, please.

06:54 PM Ruby Feature #15863 (Rejected): Add `Hash#slice!` and `ENV.slice!`

## Add `Hash#slice!`
In https://bugs.ruby-lang.org/issues/8499 we added `Hash#slice`.
`Hash#slice!` removes and returns the key/value pairs matching the given keys:
```ruby
h = {a: 100, b: 200, c: 300}
h.slice!(:a) # => {:a=>1... bogdanvlviv (Bogdan Denkovych)
