that was one line of inquiry that laura explored. Using multiple parsers
to do the job. Now using multi-parsers of different types..i am not sure
that woudl be possible..hmmm...interesting... id ont see why not...nothgin
theorically standing in the way..if they share a common scanner...dont
see why not...bnut one possiblilty is to have multi say, bison parsers
that handle various point of the grammers, then havea master parser(maybe
ahnd writtent) switch between the differ parsers...
then they all build a single AST or something...maybe one
pass generateion...

definatly something to consider.
