But maybe your patch is better for some purposes while my macro is better
for others.

Not an infinite plane obviously, since meshes can't be infinite.

With my macros user-defined deformations are very easy simple.
This is a simple twist:

#macro deform_mezz (P) vrotate(P,120*x*P.x) #end

How would a user-defined twist look with your patch?
(I do *not* mean the build-in twist-deform. I mean user-defined function!)
