[BUG] Derived types not resolved in TypeScript 3.9

See original GitHub issue

To reproduce:

  1. Make a type with a derived member
  2. See that ResolveState correctly unwraps the Derive type in TS 3.8: image
  3. Change TS to 3.9 and see that the type is no longer unwrapped: image
  4. Any attempt to use the derived state will not compile.

Not sure if this is a TS bug or just a result of stricter type checking in 3.9…

Next release will fix this once and for all, also giving some new capabilities. Stay tuned tomorrow 😄

Okay, this still does not fix Derive… but it is necessary to move to TS 3.9. So the derived is the way to go as that is the only way currently known to handle the circular typing of derived state.
