The previous phrasing ("A constant expression is ... a literal string
where any interpolated expression is a compile-time constant ...") was
ambiguous: did it mean "... where at least one interpolated expression
is a compile-time constant ..." or did it mean "... where every
interpolated expression (if there are any) is a compile-time constant
..."?
Clearly the intended meaning is that all interpolated expressions are
required to be compile-time constants, otherwise we would allow
nonsense like this:
void f(int i) {
const x = 0;
const s = "$x $i"; // Ok because x is const (!)
}
Changing the word to "every" avoids the ambiguity.
