Yes `this` is used as a "completely-replace output." A free function
with a return value doesn't work, because there are a few different
flavors of url (url, static_url, and possibly a couple more if users
request them). They differ in how they obtain their storage. But they
use url as a base class. So having `url::resolve` a as member function
makes it all work out.
