Subject: [ruby-core:80580] [Ruby trunk Bug#13404] Hash#any? yields arguments to lambdas with proc semantics

Issue #13404 has been reported by nelhage (Nelson Elhage).

----------------------------------------
Bug #13404: Hash#any? yields arguments to lambdas with proc semantics
https://bugs.ruby-lang.org/issues/13404

* Author: nelhage (Nelson Elhage)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-darwin16]
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
```
l = ->(a, b) { true }

# Raises; Uses Enumerable#all?
{1 => 2}.all?(&l)

# Does not raise; Uses specialized Hash#any?
{1 => 2}.any?(&l)
```

The `Enumerable` behavior was changed (correctly) in #12705, but the `Hash#any?` implementation (introduced in r46866) still allows the lax behavior.
