That is already a known suggestion in the pipeline

I had also suggested this earlier, it can be quite useful. I hacked
this in a locally built version by adding "#static" variables. These
were identical to those using "#declare" except that they were not
cleared after parsing, so they were available in another frame or
even for different renders as long as POV-Ray was not closed.

This worked fine in principle although the only way to free the memory
hogged by a static variable was to render a script that "#undef"-ed it.

Unfortunately the fix is based on an old beta. I was thinking
to submitting this as a patch after 3.7 final is out.
