Well, you do have a state monad to work with. Why not just stuff
the number 305 into your state, keep reading until you've read 305 bytes
(decrementing the count as you read), and return the 305-byte string
as your result for this parser? When you resume, you should
be ready to parse the next very token after the 305-byte string.
It's unclear to me exactly how to mix the IO monad with Parsec. It
doesn't really seem to be doable.
Not to mention that if hGetContents is used, the Handle has to be put
into non-buffering mode, which means one syscall per character read.
Terribly slow.
Does it? I didn't think so ...
Keean.
