All right, this would work.

But i want to keep it as simple as possible, doubling the number of macros
and having several additional helpers macros would not exactly simplify
things.  Also the CSG macros (difference, etc.) right now can take any
other function too.  The 'B' version would be more restrictive.  And
infinite shapes (only 'plane' right now) would lead to nonsense results.
