  The problem is that a #macro is *not* a function. It's much closer to
the substitution macros in a C preprocessor.

  When POV-Ray encounters a name, and this name has been declared as a
macro, it will start parsing that macro, substituting the name with the
contents of the macro.

  I'm not saying this is a good thing. I'm just saying how it works.
It might also require quite a lot of redesigning to change this (which
is exactly what POV-Ray 4 is for.)
