True, but if the language has a proper design the grammar maintenance is not
that bad.
There are syntax complete ANTLR grammars for all Java versions out there,
and i would consider Java a non-trivial language.

Maintenance has to be done from one version to the next one, and as we all
know POV-ray is not released very often.

Take it as a chance for a clean implementation, not as a annoying thing to
do.
