It's a misnomer (like others) a failed attempt to introduce "real"
literals for all types of classes. "Real" literals would be given by
const qualified register variables in file scope (which are
unfortunately not allowed.)

My guess is that the analogy is not taken from literals for arithmetic
types but from "string literals", which aren't "literals" either, but
unmutable objects.
