flatten_with_optional_argument(level=-1)

Recursively flatten any contained Arrays into an one-dimensional result. Adapted from rubinius‘

flatten_with_optional_argument!(level=-1)

Flattens self in place as flatten. If no changes are made, returns nil, otherwise self. Adapted from rubinius‘

repeated_combination(num) {|[] if num == 0| ...}

Note: Combinations are not yielded in the same order as MRI. This is not a bug; the spec states that the order is implementation dependent

repeated_permutation(num) {|[] if num == 0| ...}

Note: Permutations are not yielded in the same order as MRI. This is not a bug; the spec states that the order is implementation dependent!!!

shuffle!()

Standard in Ruby 1.8.7+. See official documentation
