However, by default there are no empty objects (although there are 
proprietary ways like assigning to the `__proto__' property to create them, 
leaving a from then on crippled object).  Even Object instances inherit from 
Object.prototype by default.

As a result, some property names (like "toString") are already used.  So you 
should avoid assigning to the corresponding properties in order to store 
user data.  Which points out *again* _that there are no *built-in* 
associative arrays in ECMAScript implementations_ (but you can try to 
emulate them, like with jsx.map.Map [1]).
