[ruby-core:100964] [Ruby master Bug#17197] Some Hash methods still have arity 2 instead of 1
From:
matz@...

List:
ruby-core #100964
Issue #17197 has been updated by matz (Yukihiro Matsumoto).
Status changed from Open to Rejected
It is caused by a historical reason. I don't think it's worth breaking compatibility, at least for Ruby3.0. Maybe for 3.1?

----------------------------------------
Bug #17197: Some Hash methods still have arity 2 instead of 1
https://bugs.ruby-lang.org/issues/17197#change-88624
* Author: marcandre (Marc-Andre Lafortune)
* Status: Rejected
* Priority: Normal
* Assignee: nobu (Nobuyoshi Nakada)
* ruby -v: ruby 3.0.0dev (2020-09-26T17:38:39Z master 950614b088)
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
`Hash#each` was changed recently to have arity of 1.
All other methods of `Hash` should behave the same.
Much has been fixed since #14015, but some remains:
```ruby
# Some methods consistently have arity 2:
{a: 1}.select( &->(_kvp) {} ) # => ArgumentError (wrong number of arguments (given 2, expected 1))
```
All in all: `%i[select keep_if delete_if reject to_h]` have their arity still set at 2.
