  21 // Important points about the AS3 Object class:
  22 //
  23 // prototype is a static, read-only property. It doesn't have the same
  24 // role in AS3 as in AS2. You can assign properties to the prototype
  25 // member, but you cannot change what it points to.
  26 //
  27 // The prototype property provides dynamic inheritance. Normally, inheritance
  28 // is done using a Traits object (bytecode, not available to AS). These two
  29 // mechanisms are separate.
