Mixin for extending ruby array with :recursive_flatten method (as supposedly it should be used often). Used default tests (instead of rspec) for simplicity
# frozen_string_literal: true
class Array
module Mixins
# Mixing for providing flatten method into Array
module Flatten
# Returns a flatten copy of array
# Example: [[1,2,[3]],4].recursive_flatten => [1, 2, 3, 4]
def recursive_flatten(result: [])
each do |element|
