When I said "closures are used ...", I wasn't trying to be preachy
about how I think callbacks should be implemented, just explaining the
use (and usefulness) of *closures*.  I'm not saying closures are the
only method of implementing stateful callbacks, nor that they're the
best method around in all circumstances.

I was simply responding to a subthread that only evaluated closures as
a SICP-style OOP implementation mechanism.  That is missing the point
of closures.
