Review Comment:
I wonder if it would not be better to have a new overloaded version of the
function uuid(type) function where the parameter is the UUID type number ; we
could support 1 to 7 or 1 to 8.- dependaing on how we feel about custom. This
would then pick out which uuid to generate. Or do you see no need to expose the
others?
