Before you get too carried away with that, I'd like
to make it clear that in my version of the semantics
of 'new', it *not* work that way -- 'a' would remain
bound to the last cell, and therefore the last value,
that it was given by the for-loop.

I considered that a feature of my proposal, i.e. it
preserves the ability to use the loop variable's value
after exiting the loop, which some people seem to like.
