This method behaves identically to Ruby's SecureRandom#uuid,
generating a random v4 UUID (with only the version and variant being
constant/determined).

Please let me know if there's a way to do this that involves fewer allocations 馃檪

Have you seen these api docs?

Yes, we already have UUID.random that doesn't allocate. Please use it :-)

Not sure how I missed that. Sorry!

Probably because it's reversed from Ruby (SecureRandom.uuid => UUID.random) since we have an UUID type.
