Plus, for backward compatibility, make sure that str(importerobj)
returns something which resembles a non-existing directory.

Note that the builtin importer skips non-string entries
in sys.path, so the above will only be needed for existing
import hooks.

Still, I would like to rephrase my 0.02EUR which I already
posted twice... why not start to think about what these
importers would do first ? If there are only a handful of
wishes we could just add them to the builtin machinery and
be done with it...
