std.algorithm.sort is a template, so it has access to the fully derived
class type. The compiler simply rewrites a < b as a.opCmp(b), which calls
his function if you are using the derived type.
Without defining opCmp as taking object, however, the builtin array sort
would fail with a hidden function error.
