Yes, an f-string is really a form of expression, not a literal. But
prior art has generally been to have similar constructs referred to as
"interpolated strings" or similar terms:
https://en.wikipedia.org/wiki/String_interpolation
Plenty of languages have some such feature, and it's usually
considered a type of string. Notice the close parallels between actual
string literals used as format strings ("I have %d apples" % apples)
and f-strings (f"I have {apples} apples"), and how this same parallel
can be seen in many other languages. Yes, it may be a join expression
to the compiler, but it's a string to the programmer.
