Description Jean-Yves Avenard [:jya] 2023-10-31 23:46:36 PDT

Right Now, you can only chain identical NativePromises.
`NativePromise::chainTo()` requires a NativePromise::Producer of the exact same type.

It would be nice if we could chain promises so long that their resolve/reject type are convertible into the other.

e.g. chain a NativePromise<void, int> to a NativePromise<void, long>
