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.
