Array destructuring each triggers false match Style/HashEachMethods

[jcoyne]

In rubocop 1.58.0 this code triggers Style/HashEachMethods.

arry = [[1, 2], [3, 4]
arry.each { |_x, y| puts y }

If you correct it you get the error:

undefined method `each_value' for [[1, 2], [3, 4]]:Array (NoMethodError)

Clearly de-structuring in a block is not sufficient evidence to determine the callee is a Hash.

This issue is a dup with #12444.

And, RuboCop cannot determine the type of the receiver, this cop has already been marked as unsafe:
https://docs.rubocop.org/rubocop/1.58/cops_style.html#stylehasheachmethods

Moreoverer, you can address this issue with the following configuration:

# .rubocop.yml
Style/HashEachMethods:
  AllowedReceivers: ['arry']
