And here I've been working on adding these very same features to my
ofuncobjects. I'm really think that this is the "right" place to do this,
and then to produce a single omathmodule.c that does the right thing
efficiently for all object types. Let's talk off-line about this Konrad so
we don't end up duplicating each others efforts here.
