+#### `reactionRequiresObservable: boolean`
+Warns when a reaction (eg `autorun`) is created without any observable access.
+Use this to check whether you are unneededly wrapping react components with `observer`, or to find possible related bugs.

 #### `computedConfigurable: boolean`
 Allows overwriting computed values. This is useful for testing purposes *only*. Don't enable this
  on production as it can cause memory-leaks.
