Round 2 of review:

* Converted pre-existing trace!s back from debug!
* Computed `cur` from the top-most frame instead of storing it.
* Wrapped to 80 columns.
* Removed prev_active and all_candidates from `BacktrackStack`
* Removed unnecessary type annotations.
* Called activation_error() only when starting to backtrack, since it bailed
  early when passed an error anyway.
