Note that this doesn't play well with regular [1] value types
becuase e.g. you don't have control over the synthesized
bit-blit for this(this) and so you can't assume that structs
with a single pointer member are updated atomically, even if
would write the opAssign that way. In C++17 atomic_shared_ptr
has it's copy-constructor and assign operator deleted. You can
only do atomic<T> like ops with it and derive a plain
shared_ptr<T> from it, kind-of like core.atomic's
HeadUnshared(T).
Huh? Why opAssign can't just do what atomic<T> does?
opAssign is fine, the problem is with the this(this).
