Happy, again

[Frank-Andre Riess]

Hi folks,

having set up some monadic type for usage with Happy, I've encountered
some thing that puzzles me: as it seems, once happyError gets called, you
cannot get back into the parser "loop" even if you return some `Failed
xy::ParseMonad' instead of calling error. How and where do I catch such an
error and can I really cope with most "unexpected errors" this way (even
at the beginning of the input)?

Thanks in advance,
Frank-Andre Riess
