What's your use case, except for not breaking existing code?  Apart
from the latter, I can't think of a single use case that isn't served
just as well by *copying* the object reference into another variable.

BTW perhaps we should add the same semantics and syntax to 'with expr
as var'? I can't think of a reasonable use case for keeping var alive
after the with-statement terminates either. (Nor for using anything
more complex than a local variable, BTW.)
