If you change opCmp signatures to: int opCmp(const S rhs) const int opCmp(const ref S rhs) const // may work in general or: int opCmp(const S rhs) const // may work in general if S allows lvalue copying or: int opCmp(S rhs) const // In this case, sorted elements is always mutable so it works or: int opCmp(const ref S rhs) const // In this case, current std.algorithm.sort implementation only requires // lvalue comparison, so it works) Then you can compile it. > The same occurs if you use a SysTime instead of C, so the problem occurs > whether the class is directly or indirectly insed of S. This strikes me as > being similar to issue# 7808 (though not identical). That was fixed however, > and this isn't. Bug 7808 was alias this type resolution problem.
