This is an interesting topic and you make a good point. I suppose the
question is, are we going to use prototype or not? When I originally
suggested using namespaces I didn't mean to extend the object as well
as use a namespace. I personally don't think it is a good idea for a
library to 'pollute' the global object ... especially if we want to be
compatible with other libraries and be future proof.
I still think that using a namespace and providing a short cut like $A
is the best way to handle this, instead of extending the element or
prototype. I think we could even get chaining to work properly if we
really wanted too. We could also probably provide a way to extend the
prototype if users really wanted it.
