@tvald When new <T extends void>(executor: (resolve: (value?: T | PromiseLike<T>) => void, reject: (reason?: any) => void) => void): Promise<T>;
new <T>(executor: (resolve: (value: T | PromiseLike<T>) => void, reject: (reason?: any) => void) => void): Promise<T>; |

My previous code is not extensible for classes in the current compiler. Fixed as follows. new <T>(executor: (resolve: [T] extends [void] ? (value?: T | PromiseLike<T>) => void : (value: T | PromiseLike<T>) => void, reject: (reason?: any) => void) => void): Promise<T>; |

Fixes #11094, #3356. Replaces the approach in #19633 with a conditional typing of
