Provide some transforming interface to dispatch one type as another type

[CzechsMix]

Provide some interface or API for providing a conversion from type A to type B so that when A is disptached, an instance of B will be dispatched to handlers, either in addition to or in lieu of.

Use case

// pins the types that can be assigned to outcome instead of just "object"
Either<Some.Success, Some.Error> outcome = await doWork();
_dispatcher.Dispatch(outcome) 
// wouldn't disptached Either<A, B>, but would unwrap 
// the either and dispatch the underlying value.

Some ideas

public interface IDispatchTransformer
{
  public bool AppliesTo(object obj);
  public bool ReplacesOriginal { get; }
  public object Transform(object obj);
}
