Typescript issues

[avlonder]

Using the decorate function of MobX5, if I cannot use persist with one of the three optional arguments (object, list, map), without TypeScript throwing an "No overload matches this call".

Moreover, you can feed whatever string you like to persist without getting any TypeScript error.

I had a short look at the code, but I don't see how to patch it.

The error is gone if I set strictFunctionTypes to false in tsconfig.json. Still no clue how to apply a real fix.

Ok, I found the solution: in the type declaration of persist, you should change key: string to key: string | symbol.

Since this library has not been maintained for years, this is a consequence of an old issue in MobX: mobxjs/mobx#1713.
