Infer result type when available in `.deserialize`

[jokull]

Basically I'm having to do this:

const result = Result.deserialize<
  Extract<typeof serialized, { status: "ok" }>["value"],
  Extract<typeof serialized, { status: "error" }>["error"]
>(serialized);

But even here, because serialized is typed, we don't need to check Result shape and .

In fact ... what I want when my stack has the serialized shape is to just do this:

if (serialized.status === "ok") {
  result = new Ok(serialized.value);
} else {
  result = new Err(serialized.error);
}

So maybe I just want Result.fromSerialized or Result.new?
