Module symbol 

Boa’s implementation of ECMAScript’s global Symbol object.

The data type symbol is a primitive data type. The Symbol() function returns a value of type symbol, has static properties that expose several members of built-in objects, has static methods that expose the global symbol registry, and resembles a built-in object class, but is incomplete as a constructor because it does not support the syntax “new Symbol()”.

Every symbol value returned from Symbol() is unique.
