Everyone who ever uses C++ uses move semantics all the time,including move elision. It's not an obscure feature.

I've been using C++ for years and I have no idea what you could be possibly referring to. The hardest aspect of move semantics is basically the rule of 5. From that point, when you write a class you have the responsibility to specify how you want your class to be moved and how you want your moved-from class to look like, provided that you ensure you leave it in a valid state.

That's it.

What exactly do you believe needs fixing?
