Please don't use __all__. At the moment, __all__ is the only way
to easily tell whether a particular module object really represents
a package, and the only way to get the list of submodule names.
If __all__ is overloaded to also represent exportable symbols in
modules, these two pieces of information will be impossible (or
require much ugly hackery) to obtain.
