[webkit-dev] Adding new JS bindings, having "slight" problems

Good day, Nebojša.

Overall I am with Adam, that if it's ECMAScript feature it should go
in VM itself (JavaScriptCore or v8).  However, as a prototype hacking
bindings might be easier.

What exactly you're trying to achieve here?  Speaking of v8 you might
either describe all the properties and methods your instances would
have (v8 supports class-like inheritance model) or set your own custom
constructor which would do whatever you want with your instance.

How do you want your static function look in JS?

Are you talking of JSC or v8 bindings here?
