If the open-bracket is not preceded by a value (or a sub-expression which yields a value), it is interpreted as the beginning of an array literal. For example, [a, b, c] is equivalent to Array(a, b, c)

It is invalid because strings have no members by default. As you showed, it can be valid.Helgef wrote:As I said, it is invalid, because you cannot member access a string.
