💻 Code

Code below compiles

export interface Controller {
  handle<T>(httpRequest: HttpRequest<T>): HttpResponse<T>;
  handle<TRequest, TResponse>(httpRequest: HttpRequest<TRequest>): HttpResponse<TResponse>;
}

Code below does not compile

export interface Controller {
  // handle<T>(httpRequest: HttpRequest<T>): HttpResponse<T>;
  handle<TRequest, TResponse>(httpRequest: HttpRequest<TRequest>): HttpResponse<TResponse>;
}

Code below does not compile

export interface Controller {
  handle<T>(httpRequest: HttpRequest<T>): HttpResponse<T>;
  // handle<TRequest, TResponse>(httpRequest: HttpRequest<TRequest>): HttpResponse<TResponse>;
}

🙁 Actual behavior

Code does not compile when removing any of the overloads.

🙂 Expected behavior

Since having an overload in Controller.handle works, having just one member with the correct signature should also work.
