Monadic bind is very, very handy for parsing, giving you context
sensitive parsing if you need it.

If you have a grammar that is LL1 plus helpers (i.e. the extended
Kleene operators - many1, sepBy etc.) then applicative formalism is
nice and as Doaitse Swierstra has shown provides good opportunities
for optimization; but I'd hasten to call it a better match in general.
