Detailed Description

Design Questions:

• When a c++ object returns a new object represted by one of its members, should it return the same javascript object each time as well? class Thing { OtherClass other_class; OtherClass & get_other_class(){return this->other_class;} <== should this return the same javascript object on each call for the same Thing object }
  • that's currently what the existing_wrapped_objects map is for, but if a new object of the same time is created at the same address as an old one, the old javascript object will be returned.
    • how would you track if the c++ object source object for an object went away?
    • how would you actually GC the old object when containing object went away?
  • Maybe allow some type of optional class customization to help give hints to V8ClassWrapper to have better behavior
