Lex and yacc debugger design

As part of a third year project I am building a debugger for lex and
yacc, percifically flex and byacc. It would be very useful to me if I
had user opinions on which error messages are inadequate, how they could
be improved and which bugs in lex and yacc code are totally overlooked.


Thanks

[I find that the problem isn't getting the yacc or lex source to compile,
it's figuring out why it's not lexing or parsing the language I think
it is. Single stepping and being able to see what the state machine
is doing helps here. -John]
