For relocating, I'm sure the language will provide a solution and compilers 
will likely give us a grace period to adjust. I don't think there are many 
people (I don't know any) that oppose the idea of relocating objects, even if 
they oppose the actual solution chosen to do that (like a core language 
extension to provide a destructive move constructor or a moving destructor).

Actual C++ primitive types won't be affected because they are trivial. My 
point again is that we are doing that for non-trivial types.
