In modern generics-oriented C++ I would say:

void foo(T); // by value - and probably not what you want
void foo(const T&) // copy semantics overload
void foo(T&&) // move semantics overload

Please keep in mind that C++ do perfect forwarding of those 
rvalue references when you pass it down a call chain.
