I *like* this way of doing autoclose files. Much better than the way
I've been thinking

    f = autocloser("spam")
    with f:
        ...

On the other hand, I quite like

    with lock:
        ...

(where lock is defined appropriately).

I don't know. Does the fact that the same statement is best used in
two subtly different ways (permanent object vs throwaway helper
object) count as a disadvantage of the statement (in terms of
teachability, if nothing else...)?

Sigh. I'm *so* glad I'm just skimming the thunk discussion - I don't
think my brain would survive the details :-)

Paul.
