	My concern here would be that potentially calc function naming is not
always a great match to UNO constraints - and yet those functions are
defined as IDL. Some functions have '.'s in them IIRC, others might want
to have _'s (?) and translating functions is prolly not feasible via the
UNO interface.

	It's not clear to me that scaddins/ (beyond providing a nice test /
example for how to implement UNO functions as extensions - which is
good), is going to cut it long term.

	ATB,

		Michael.
