+#### unsafe mode
+
+normally, pre hooks prevent you from inserting into the hooked range
+when the hook is triggered. However, sometimes you do need to do this.
+In those cases, pass in a range with `{start: START, end: END, safe: false}`
+and level-hooks will not error. If you use this option, your hook must
+avoid triggering in a loop itself.
