Sure - but actually my main point was to have a uuid() call you could use 
to just get whatever the platform's preferred form of GUID is, without 
having to pick what *type* you want.

The idea being that there should be some call you can make that will always 
give you something reasonably unique, without being overspecified as to the 
type of uuid.  That way, people can be told to use uuid.uuid() to get 
unique IDs for use in their programs, without having to get into what types 
of UUIDs do what.

Perhaps that isn't feasible, or is a bad idea for some other reason, but my 
main point was to have a call that means "get me a good unique ID".  :)
