I don't think that's right. In C++03, unique_ptr has a unique_ptr(unique_ptr&) constructor. And the C++03 std::move is: template<typename T> T &move(T &v) { return v; } So... the "explicitly moved for C++03" call to std::move in map appears to also be redundant (and pessimizing) in C++03. In fact, in C++03, std::move appears to *always* be a no-op.
