Define instance member properties in class 'HttpClient ' as instance member methods

[SaschaGalley]

Instead of rewriting the templates, I want to be able to extend the underlying HttpClient class, e.g.:

class ApiWithErrorHandling extends Api<any> {

  async request<T = any, E = any>(params: FullRequestParams): Promise<HttpResponse<T, E>> {
    try {
      return super.request(params);
    } catch (e) {
      // do error handling (e.g. logout)
      throw e;
    }
  }

}

which results in the following error:

Class 'Api ' defines instance member property 'request', but extended class 'ApiWithErrorHandling' defines it as instance member function.

Is there any reason, why the HttpClient class is designed that way?
