+* Remove the `empty` constructors for DFAs and replace them with
+  `never_match` and `always_match` constructors.
+* Consider refactoring the NFA representation such that it can be instantly
+  loaded from a `&[u8]`, just like a sparse DFA. Main downside is that this
+  could negatively impact using the NFA with deserialization costs. Before
+  doing this, we should write PikeVM and backtracking implementations so that
+  they can be benchmarked.
+* Add captures and anchors to NFA.
+* Once we're happy, re-organize the public API such that NFAs are exported
+  and usable on their own.
