Could you write argument names for non-trivial cases?
  v8::Local<v8::Object> instance,
  v8::Local<v8::Object> prototype,
  v8::Local<v8::Function> interface,
  v8::Local<v8::FunctionTemplate> interfaceTemplate

Also better to follow Chromium's coding style (i.e. wrap lines for each
argument).

Done.
