  Impossible in the general case.

  Besides, you are assuming that there is a single unambiguous "loop condition
variable". The condition in the #while construct can be *anything*. It can be
a complex expression, it can be a function or macro call, it can contain a
condition composed of many variables...

  For example, if you had something like this:

#while(xCoord * 2.5 < yCoord * 5 & sqrt(zCoord) < 10 * zSize)

how would POV-Ray check that this isn't an infinite loop?
