It isn't that simple.  Like passing spline and function evaluations to macros,
it requires an extra token of lookahead, and the parser isn't made to be able
to handle that.

I do think splines and functions should have the same limitations, though, and
currently they do not.  Functions act one way and splines act the opposite way.
