Can we use template to unify these two functions? Then we can have
v8ConstructorAttributeGetter() only.

[Yuki, 2015/03/03 07:03:53]

Yes, it's possible.
However, as we talked offline, it's better to use non template functions when we
store the address of functions because it's clearer which version of functions
is referenced.  e.g.

const V8DOMConfiguration& attributeConfiguration = {
  v8ConstructorAttributeGetterAsProperty, ... };

+void v8ConstructorAttributeGetterAsAccessor(const v8::FunctionCallbackInfo<v8::Value>&);
+
 typedef void (*InstallTemplateFunction)(v8::Local<v8::FunctionTemplate>, v8::Isolate*);
