Useful analogy for URL/URN/URP distinctions

The following analogy, or rather an expansion of it, came
to me during a related discussion on the RDF Core WG list
regarding "what is a resource"...

That's an interesting way to look at it, and in fact, a
useful analogy for the difference between URL/URN/URP
is that a URL is a function, a URN is a pointer to a
function (possibly null) and a URP is a constant.
