$value
$value : mixed
Base object, mother of all classes of this package.
It contains some validation processes, basic magic getter to get internal
value and __toString() feature.
mustBeStringOrScalar(mixed $arg, string $arg_name) : void
Checks whether given value is string-like or scalar type.
Value must be of string-like type (string or object having
