As I remember it (Pierre M can probably correct me) the recfunctions
are not ports of the mlab functions, but are considerably extended in
order to deal with masking, and do not have exactly the same API.
When I noticed this I wondered if there would be some sensible way of
making the mlab routines available in a separate namespace, but I did
not pursue it.
