I appreciate hearing your insights into the Tamarin code; that helps me
understand it, and where it stands in the bigger picture. Good to hear that
you are continuing your efforts with WebKit.

Now as to the larger question I intended to raise:
is it worth doing much to the current JS code, or will that all soon be
moot, as people's focus shifts to the next generation of JS? Perhaps that
next generation will require a total re-think anyway?
