Come to think of it, it might be possible to consider reintroducing ^
now. 

I think the only reason for considering the non-standard precedence was
to make it easier to port scenes from Megapov 0.* which happened to use
an unusual precedence order. At the time, lots of people were converting
isosurface scenes from MegaPOV 0.* to the POV beta that as experimenting
with ^.

Now that MegaPOV 0.* has been superseded for quite a while by MegaPOV
1.*, which also doesn't have the ^ operator, it could be introduced with
standard precedence without upsetting anyone.
