* In `examples/` and `benches/` I simply do .unwrap()
* In tests I do `.expect("#[cfg(test)]")` to make reviewing the diff
easy
* In deprecated methods I do .expect("<deprecation message>")
* In `uses_backrefs = uses_backrefs || proto_ids.iter().any(|id|
syntax_set.get_context(id).unwrap().uses_backrefs);` I do an
`.unwrap()` because `?` does not work inside of `.any()`. But that can
be fixed later if necessary without semver breakage.
* To keep the scope of the PR manageable I do `.unwrap()` in
`ContextReference::resolve()` and `impl<'a> Iterator for
MatchIter<'a>` to not have to propagate an error further. That will be
done in a follow-up commit.

Finally a note on chaining many PRs together: I do that sometimes, but normally I have not written or at least not polished the code that comes next. Stacking many PRs on top of each other risks creating quite gnarly conflicts in case other PRs are merged in between or if you have code review comments on the first PR in a set, that other PRs depend on. So to be as efficient as possible in terms of man-hours (rather than calendar-hours) I prefer to take one step at a time in the right direction.
So if it is OK with you to keep our current pace, that is very much OK with me too.
This is one step towards resolving #98
