It sounds like what you really want is to detect the names *exported*
by the module, then.  Why not do it the same way Python does it?  If
the module defines an "__all__" attribute, then it is taken to be a
sequence of strings which are the exported names.  Otherwise, the
exported names are taken to be all the names in the module dict that
don't begin with an underscore.

Cheers,
