"The member function e.opCast() is called, and the return value of opCast() is implicitly converted to type. Since functions cannot be overloaded based on return value, there can be only one opCast per struct or class."
I've come across a situation where opcast to different types would be very useful. Why can't this be overloaded to cast to different types as a special situation for overloading on return types. Very useful IMHO.
