I agree that it is impractical to fight existing industry trends. But I
believe that there are real technical limitations to the traditional
approaches. I would say that this is research that will stay on the fringe
for at least five years, but it could change the entire field in ten.

Sorry, but I'll have to turn the accusation around. Simply because yacc and
lex are so well understood, most language designers assume that they are the
"best" paradigm to use.

Our view of a problem is mostly determined by the paradigms we understand.
I see this discussion as an attempt to get away from the traditional
Dragon Book paradigm; I don't necessarily think the Object-Oriented paradigm
will be better, but I welcome the attempt to try something new.
