The above code is illegal in C and C++, without question the most commonly
used programming language around today.  Many other well-designed languages
do not promise you that they do the minimum either (with a few very specific
exceptions, but that is not the point).  The example you provide is simply
extremely bad programming style and it is neither a bug nor a limitation on
part of POV-Ray that the above does not work.
