I would love to see an example where you would need such a construct.
Perfectly reasonable request! Maybe there aren't as many cases when
multiple variables need to be initialized to the same value as I think
there are.

As I see it, there are 2 issues:
1. Repeated evaluation of an expression: "dict()" would be evaluated as
many times as necessary. In other words, it's an unlimited generator.
2. Lazy unpacking: unpacking normally continues until the source is
exhausted, but here you want it to stop when the destination (the RHS)
is satisfied.
It just happens that in your use-case they are being used together.
