The new code looks worse?

What's wrong with comparing a Ref<> with a C++ reference? I can compare a RefPtr<> with a raw pointer already so why is this different?

[Alex Christensen]

That's exactly what I'm trying to do in bug 224412 but can't until I do this.  This compares a Ref<SharedBuffer> and a SharedBuffer& by calling SharedBuffer::operator== which compares the bytes contained in the SharedBuffer's segments.  What I want is a pointer comparison, which is why I have to make these two call sites look worse before introducing a generic Ref equality operator without breaking them.

Oh, I missed that. Yes, I agree then.
