If it is so strongly optional - it sounds like it would be used
rather seldomly, if at all - why make these hints such a central
point of the interface?
If they're not, I'd have parse() return undef until it can return
the request object. This is usable as a boolean and results in
code like this[1]:
do { $data = get_data() } until $req = $httpp->parse($data);
Those interested could use an extra method to ask for a hint
about the amount of data expected/required.
[1] Or even
1 until $req = $httpp->parse(get_data());
