I can't see the page you refer to but I also don't see how knowing
the number of records already processed (which your function can
count itself pretty easily) can tell you how far along you are.
Knowing how many are left would require that you somehow know how
many objects will ultimately be processed. Such information is, in
most cases I can think of, simply not available. It's like asking
how many words I will type today. Moreover, this 'count' could be
different at every step in the pipeline. Maintenance of all these
counts represents an amount of overhead I'd just as soon not have
every application I write saddled with. Especially when I can't
think of even one practical use much less enough uses to consider
that it might possibly be justifiable.
