-- RE rewrite --
- [ ] look at bailing early from running the VM to go back to aho-corasick if
      all threads die?
  - could be another large speed up but would need to contend with the unanchored
    matching instructions that wrap all VM programs


-- Misc / Editor features --
- [ ] support running an exec script from a file
- [ ] Add command & Edit history using minibuffer with hidden lines

-- Structural regular expressions --
- [ ] Storing the history of previous edit commands and allowing for cycling through
      them would be helpful (same for Command mode).
