Generating a GUID/UUID in KRL

Is there a built-in function in KRL for generating a GUID of 开发者_如何转开发UUID (or something similar)?

I've created a module that wraps a webservice that might hold you over: UUID Module

Use like so:

ruleset a8x165 {
    meta {
        name "UUID Module Example"
        description <<
            Example use of the UUID Module
        >>
        author "Sam Curren"
        logging off
        use module a8x164 alias uuid
    }

    dispatch {}

    global {}

    rule first_rule {
        select when pageview ".*" setting ()
        pre {
            testuuid = uuid:new_uuid();
        }
        notify("Hello World", "This is a UUID: #{testuuid}");
    }
}
