Nope, no trick at all. The parser will have a list of functions--if it sees
function X, it loads in module Y. (Possibly version Z) Nothing fancy needs
to be done.

The list of functions that trigger this automagic use-ing of modules should
be reasonably small. The point of this is *not* to eliminate all the "use
Foo;" in code, rather it's a mechanism to extend the (possibly smallish)
set of builtin functions without requiring extra "use Foo;"s.
