The wording about string literals in question is not under Syntax, so I would
not expect it to be a syntactical property. If it is meant to be interpreted
syntactically however, then I would expect the following declaration to also be
invalid:
int x={0,};
Since {0,} is not syntactically an expression, nor an expression enclosed in
braces. Therefore it should not be a valid initializer for an object with
scalar type.
