I don't see that being able to reuse elements adds any value. Could you
give an example where it does?
The global eval equivalent is an example. It's not much of an
improvement over the cloneNode example but I'd like the performance to
be as close to a plain eval as possible. Ability to switch type,
charset, language attributes in chosen user agents may be useful for
things like testing E4X support or ES4 support, or correct broken
encodings. Ability to execute an external resource again may be
useful. All of these are already possible however, so I don't think
they are strong use cases.
If there aren't any strong use cases I think we should go with what's
simple.
