Overall, won't WithUndefinedOrNullCheck attribute do what you are looking for?

In general I am not sure (but I didn't check) that the current implementation correctly processes null, but if your policy regarding null is different, I would still suggest adding another policy to V8Parameter instead of brand-new attribute.

May you give it a try?

And probably add a test to see what happens with new WebKitCSSMatrix(null)

> Source/WebCore/bindings/v8/V8Binding.h:390
> +            if (m_v8Object.IsEmpty())

I would put it differently: if (m_v8Object.IsEmpty()) {  setString(String(); return true; } and remove all special cases below.
