Advantages

• Small overheads (Significantly faster than ES6 Proxy)
• this is unique and identical for each instance

Known Limitations

Architectural Limitations

• Class !== Class.prototype.constructor
• new Class() is not trackable
• new Class.prototype.constructor() or new (wrap(Class))() is trackable
• Properties without setter/getter are not trackable

Current Design Limitations

• Inherited properties are not tracked
• Generation of setter/getter for properties are not implemented
