That would work perfectly ... if I was using Py's parser (Ox) instead
of
the parser use by Dot. At this time I would rather not implement such
a heavy rewrite (although I probably will one day anyways) so this is
not
really an option (at least not a simple one). (When I do finally give
in
and attempt a rewrite of Dot, I will most definitly consider looking at
Py and Ox to use as the parser for the new program however.)
