Symbols are not value objects, they are primitives like strings, and the
'Symbol' function is analogous to 'String'. See
http://esdiscuss.org/notes/2013-09-18
Consensus/Resolution
* Symbols are a new primitive type with regular wrapper objects
* typeof symbol === "symbol"
* implicit conversion to string throws
* new Symbol throws
* Symbols are public, not private - ok that they leak to Proxy
* Symbols are unique
* Only exposed via Object.getOwnPropertySymbols instead of
Object.getOwnPropertyKeys
* |Object.mixin| copies both symbol and string properties

Given that all upcoming value object constructors will start with
lowercase letters, shouldn’t Symbol, too?
