refactor how we handle locations so that it is only the parse_FOO
...
function that does the adaptation for optional location information (is
optional location information even worth it, or should we just default
to `()`)?

change parse_Foo so that it expects to consume entire input;

later we'll make a version called `resume_Foo` or something that
lets you supply the initial state (lookbehind, lookahead, etc)
in its entirety

change the behavior of @< and friends so that instead of supplying
...
`None`, they use `Default::default`. You can always give an option
yourself if that's what you want, after all, but most of the time
it's kind of annoying!
