Ahhh...

That makes sense, now that I see it.

Would one be able to pass signs (+ - / *), isosurface function names and 
things like atan and sin in some manner as that as well?

I've been trying to do something like this: (pardon the crapcode)
#macro isoFunction(operator, funcName, xVal, yVal, zVal, P0, P1, P2, P3, P4, 
P5, P6)
 #local isoFunc = function {operator((funcName(xVal*x, xVal*y, zVal*z))};
 isoFunc(x,y,z)
#end

#declare foo = isoFunction(x+,f_noise3d,5,5,0.1,0,0,0,0,0,0);

No joy obviously.

You wouldn't happen to know if it is possible to concat strings as variable 
names, would you? #local myObj = concat(obj + i); would be great... :-D

Thanks!
