An easier way to repeatedly create routes with the same basepath

Currently you have to write something like
 

QHttpServer server;
server.addRoute("/api/something", ...);
server.addRoute("/api/somethingelse", ...);
server.addRoute("/api/anotherthing", ...);

What would be nice is if the /api/ part could be omitted somehow, a suggestion I have is a new class that would enable something like this:

QHttpServer server;
auto api = server.withBasePath("/api");
api.addRoute("/something", ...);
api.addRoute("/somethingelse", ...);
api.addRoute("/anotherthing", ...);

Not only would this make it look cleaner, if it worked 'recursively' it would also make enabling support for reverse proxying with a base path much easier, and wouldn't need to permeate every single addRoute call, nor would there need to be a global setBasePath that affects the whole server. If your setup previously looked like the snippet above you could just make the change as below:

QHttpServer server;
auto base = server.withBasePath("/myservice")
auto api = base.withBasePath("/api");
api.addRoute("/something", ...); // => the path for this route is /myservice/api/something
...
