Subject: [ruby-core:61188] [ruby-trunk - Feature #6499] Array::zip

Issue #6499 has been updated by Marc-Andre Lafortune.

Duplicates Feature #8970: Array.zip and Array.product added

----------------------------------------
Feature #6499: Array::zip
https://bugs.ruby-lang.org/issues/6499#change-45547

* Author: Ilya Vorontsov
* Status: Rejected
* Priority: Normal
* Assignee: Yukihiro Matsumoto
* Category: core
* Target version: 2.0.0
----------------------------------------
Sometimes it's more natural to have Array::zip rather than Array#zip. Otherwise first array of list became unnecessary dedicated
For example 
cols = first_row.zip(second_row,third_row,fourth_row)
have more natural analog:
cols = Array.zip(first_row,second_row,third_row,fourth_row)

Implementation is obvious:
def Array.zip(first,*rest)
  first.zip(*rest)
end
