Subject: [ruby-core:45377] [ruby-trunk - Feature #6515][Feedback] array.c: added method that verifies if an Array is part of another


Issue #6515 has been updated by nobu (Nobuyoshi Nakada).

Status changed from Assigned to Feedback

Then why don't you use Set#subset? method?

What's the rationale that Array also should have similar method?
And why different name?

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.
