Thank you very much!

All things considered, unless there is a big performance hit for some 
reason, I'd prefer to use this method to build the user-defined function 
at parse time.  The recursive formulation always struck me as an odd way 
to iterate, and povray crashing when the function is defined at the 
"wrong" time is reason enough not to stick with it.

Besides, if the quaternion road leads somewhere fruitful, trying to 
combine all the intermediate expressions by hand would be a nightmare.
