If the operations return "type&&" instead of "type", they can potentially be more efficient, but I'm a little cautious to do that without giving it some thought because the choice implies subtle differences. I'm sure Daniel has already taken this all into consideration.
Return by value please. Otherwise:
type const& x = type() + type(); std::cout << x; // BOOM; x is dangling
Won't the following fail too, making it completely useless? void foo(type const& x) { ... } foo(type() + type()); Regards, Nate
