Do I understand correctly that you would like to have a module loader
that accepts registrations for file type handlers and whenever it
doesn't find a .beam file for a module, asks these handlers if they
can find a source file and compile+load it? That would be cool. The
only delicate issue I see right now is how to find these source files,
if the source directories aren't added to the code path.

Vlad
