When I do it wrong POV-Ray always tells me that it for example expects a
string instead of an arry.
Is there a way to check the type of a variable? Is especially interesting
now arrays can hold different types. Also gives the possibility to declare
a single instead of declaring a whole array for a single item, when inost
cases for a macro a single value suffices.
If not, read it as a feature request.
#if (type(Var)=String)
...
#end

MegaPOV had such a feature. Official POV-Ray doesn't.

Ah yes, #declare Identifier=is ( IDENTIFIER , TYPE | SUBTYPE );
I guess this feature is probably not high on the transplantation list.
