:-) just...

Thanks for posting this code. I have no feel for it at the moment, but 
would like to play. Longer term, I'll ponder the suggestions.

Initial reaction is I'm unsure how to nicely handle inputs and results 
if made inbuilt today. And, I doubt whether these things really need to 
be inbuilt functions? With the curves and derivatives themselves I 
wanted to be able to use them within the VM at render time.

Maybe these could be shipped macros in a core include file...
