An interesting idea, but what does that buy you that a plain sprintf does
not?
$pr->build( { ALBUM => sprintf("%04d", $album),
PHOTO => sprintf("%04d", $photo) } )
In this example with numbers as the keys perhaps it looks useful, but
isn't that a special case? In most cases, we couldn't do anything special
like zero-pad the numbers.
For example, if we had users in groups:
'/groups/${GROUP:\w+}/users/${USER:\w+}.html'
There's no other printf format of any interest that comes to mind, other
than %s.
