Basically, `.stringof` is what the compiler uses when it needs to
display something in an error message. If it were locked down in
the spec, then making improvements to error messages would in
some cases require a deprecation cycle.
That said, it might still be worth specifying the behavior in a
few specific cases—e.g., guaranteeing that `.stringof` on an
integer value will always produce a valid integer literal.
