How do I create a UUID (GUID) in Livecode (or HyperTalk)?

Question

How do I create a UUID (= Universally unique identifier, or GUID = Globally Unique Identifier, Microsoft speak) in Livecode or Hypercard?

The aim of UUIDs is to give practically unique keys to pieces of information without a central coordination.
