Both of those parsers are written in totally different languages from those 
used for GnuCash.  It would be equally appropriate to propose parsers 
requiring reimplementing GnuCash in Objective CAML, Java, or Ada.

In any case, the challenges in parsing QIF files would not be addressed by 
looking into a full-scale LALR-1 style parser.  The "complexities" of QIF 
could more than likely be fully plumbed with nothing more sophisticated than 
FLEX.
