-- auto-enable of strict mode depending on compiler optimizaton level
 - property binding optimization
   - would no longer allow `cleanup()` usage in binding scopes
 - solution to nested reactivity, see: SolidJS stores
-- investigate performance of wide graphs
+- optimize wide graph updating
-- optimize child removal
 - implement from solid:
   - Portal
   - batch
 - optimize `indexes()` double-diffing
 - define behavior of deriving a source within a derived source
-- review destruction of node under a root that has a child in another root
+- define behavior of node destruction under a root that has a child in another root
-- check in strict mode for forgetting to call constructor `create(class)`
 - improve crash course, some sections feel like information dumps
