Yay to Value types
and +1 for the per-realm thinking
For typeof, this would seem intuitive:
var ColorType1 = ValueType(Symbol("Color"), {...});
var ColorType2 = ValueType(Symbol("Color"), {...});
var ColorType3 = ValueType(Symbol("Other"), {...});
var ColorType4 = ValueType(Symbol(), {...});
typeof ColorType1 // "Color:s1" // where s1...sN is a generated increment/key
for a new user symbol
typeof ColorType2 // "Color:s2"
typeof ColorType3 // "Other:s3"
typeof ColorType4 // "s4"
// Global symbols use their keys prefixed by a 'g'
var ColorType5 = ValueType(Symbol.for("Color"), {...});
typeof ColorType5 // "gColor"
