[ruby-core:115809] [Ruby master Feature#20049] Destructive drop_while for Array and Hash

Issue #20049 has been updated by matz (Yukihiro Matsumoto).

Status changed from Open to Feedback

I reject `Hash#drop_while!` because the order is not (and should not be) important for Hash and the order of hash is fragile anyway.
Whereas `Array#drop_while!` has chance. Could you explain the use-case for the new method, please?

Matz.

Feature #20049: Destructive drop_while for Array and Hash
https://bugs.ruby-lang.org/issues/20049#change-105758

* Author: chucke (Tiago Cardoso)
* Status: Feedback
* Priority: Normal
----------------------------------------
I propose a "drop_while!" variant for arrays and hashes, which changes the current instance.

```ruby
h = {foo: 0, bar: 1, baz: 2}
h.drop_while!{|element| key, value = *element; value < 2 }
h #=> # => { baz: 2 }
```
