A `String` or a lazy `ByteString` will be lazy and consume
minimal memory. You can parse lazy `ByteString`s with
AttoParsec. To the best of my knowledge, the most patched up
and version of that parser is here:
It is really in your best interest to parse with `ByteString`s
instead of `String`s.
Disclosure of conflict of interest: The package I mention is my
own fork of Bryan O'Sullivan's AttoParsec (which is a little
broken in places).

In so far as it is lazy, yes.
Lazy IO. A terrible idea, except when it's a good idea.
