When I tried to create a parser for Delphi, which is a widely used
Pascal dialect, I noticed that the syntax is context sensitive. I also
noticed that the current declaration of the OPL (Object Pascal
Language) contains some elements, which are much closer to the
undelaying language philosopy, and consequently result in very short
declarations, in contrast to any Lex/Yacc or EBNF representation of
the same grammar.


Therefore I think that distinct kinds of grammars require or at least
enforce distinct syntax notifications, which cannot be merged easily
into a single approach. Otherwise you may end up in using something
like assembly language, instead of using a high level language ;-)
