Unable to create Task<T, Error> with a known Error type

[NachoSoto]

Description

I'd have expected that with typed-throws it would be possible to create a Task<T, E> with a known E, but none of the Task constructors have typed-throws definitions.

Reproduction

enum E: Error {
  case a
  case b
}

func f() async throws(E) -> Int {
  throw .a
}

func b() {
  // Referencing static method 'runDetached(priority:operation:)' on 'Task' requires the types 'E' and 'any Error' be equivalent
  Task<Int, E>.runDetached {
    try await f()
  }
}

Expected behavior

Code compiles
