What exactly do you mean with "externally callable". Do you mean that
it should be possible to recognize procedures defined with "define-external"?
This shouldn't be too hard: the lolevel unit has some functions for decorating
procedures with arbitrary data and a custom variant macro of "define-external"
could then expand into the normal define-external + decorator code.
