TL;DR: I propose the following behavior:

A difficulty I have with the idea as presented is this.
If I can say this:
"{x:d} {y:d} {z:d}" = "1 2 3"
...thus assigning 1, 2, 3 to x, y, z respectively, I might want to also do the same thing this way:
q = "{x:d} {y:d} {z:d}" q = "1 2 3"
The intent being: save the f-string as a variable, and then use it to assign later. But that can obviously never work because q would just become the string "1 2 3" .
The same problem exists for assignments to tuples, subscripts, attributes, even plain variables. I've often wanted to put an assignment target in a variable.
Feels to me akin to what Einstein called spooky action at a distance. ;) # module A x = f"{a:d}" # module B x.parse("1") assert a == 1 This seems like a joke I would want to play on someone*, not a useful feature. * well, if i were a bad person... ;) --- Ricky.
