[ruby-core:69763] [Ruby trunk - Bug #11315] [PATCH] Add Array#^ for parity with other set-like operations.

Issue #11315 has been updated by D.E. Akers.

File array_xor_vodka.patch added

The original implementation did not correctly handle the case of repeated elements occurring an even number of times in the second array. Attached is an updated version which does not present this defect, courtesy of @apeiros and his 50-proof vodka.

----------------------------------------
## Proposal

It is proposed that `Array` be given an "XOR" method which returns the symmetric difference between itself and another array.

## Rationale

`#&` and `#|` need a friend to complete the set of set-like operations on `Array`.
