Subject: [ruby-core:106113] [Ruby master Feature#16252] Hash#partition should return hashes

Issue #16252 has been updated by matz (Yukihiro Matsumoto).


We worry about compatibility. It's too hard to estimate the damage. Maybe we need a new name?

----------------------------------------
Feature #16252: Hash#partition should return hashes
https://bugs.ruby-lang.org/issues/16252#change-94708

* Author: Dan0042 (Daniel DeLorme)
* Status: Open
* Priority: Normal
----------------------------------------
Hash#partition is implemented by Enumerable so it just returns two arrays of arrays

```ruby
{1=>2,3=>4}.partition{|k,|k==1} #=> [[[1, 2]], [[3, 4]]]
```

But I think it would make more sense to behave similarly to Hash#select and Hash#reject

```ruby
{1=>2,3=>4}.partition{|k,|k==1} #=> [{1=>2}, {3=>4}]
```
