Last time I looked (sorry if I'm out of date), it had whitelists
(which implies you can load things other than on the whitelists),
nested directories (as above), and readdir(). None of these are
necessary if the complete list of modules is known at build time.
And using the mangling method we're using at the moment, no
modules can be built other than at build time.
