I don't see how it is any less intuitive than the < X, Y, Z> vector 
syntax...the user would just be specifying expressions that would be 
evaluated when the function is computed instead of at parse time. Or 
were you talking about using three separate functions?

Using macros would be too slow...and I've tried to figure out how to do 
it before, with no success. I think macros should remain parse-time, and 
that functions should be extended instead.
