But I would want any evaluation of the (sub-)object’s location to be computed once; is that where complexity could come in? I was hoping that object location determination could be done at compile-time; that’s the reason for restricting what kinds of objects can be a source object.

yes of course you have, because you already replied to John ;-)
sorry for not reading the complete thread :-/

And yes, these local bindings would effectively just be a new binding for the same memory location.
This way it really would be a compile-time alias.
