&lt;p&gt;The main focus of this ticket is tightening up input validation in&lt;br/&gt;
our V8 bindings. Doing this required normalizing the way we create&lt;br/&gt;
custom types in JS that have special C++-driven behavior. All special&lt;br/&gt;
types now use FunctionTemplates that are attached to the V8Scope object.&lt;br/&gt;
This allows us to test if an object is of the correct type before using&lt;br/&gt;
it.&lt;/p&gt;
