WHY

Unfortunately LibUUID requires the uuid dynamic library which didn't exist on my mac. This library uses Crypt::Random which doesn't suffer from that problem and should work on all Unix / Linux systems and Windows.

sub uuid-v4

sub uuid-v4() returns Str

Generate a UUID in V4 format.

sub is-uuid-v4

sub is-uuid-v4(
    Str $maybe_uuid
) returns Bool

Test if a string matches the UUID v4 format.
