Subject: [ruby-core:45369] [ruby-trunk - Feature #6515] array.c: added method that verifies if an Array is part of another


Issue #6515 has been updated by lellisga (Li Ellis Galardo).

File feature_6515_array_part_of_v3.patch added

@nobu you are right. I'll change the method to (arry1 - arry2).empty?. About the method functionally I thought of it like the subset method from Set. That's why it doesn't care about the order.

This method is like the include? method but instead of receiving a value and check if the array has it, it receives an array an check if it's part of another one.
