We have at least three issues involved here:
  1) binding JS functions to component elements,
  2) scope of JS names declared within components,
  3) binding of |this| for JS functions declared/called within components.

I guess JS folks will be open to discuss and consider options for #1 and
#2; the issues are clear and the benefits tangible. Binding |this| is a
different story. We get burnt all the time by |this| issues and sorting out
the impact is much less clear. So despite Allen's "a very simple concept",
it's playing with fire.
