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" .
