Sorry, but it's still invalid.

auto foo = bar;

will _never_ use opAssign. opAssign is for overloading the assignment operator,
and there is no assignment operator in that statement. It's a variable
declaration, not an assignment. Whether it's an lvalue or rvalue is irrelevant
for that. The difference is that with an rvalue, it's a move operation, whereas
with an lvalue, the postblit operator will be called. So, if you want to
overload the behavior of

auto foo = bar;

then you need to declare a postblit constructor:
