as you might have noticed, I went ahead and checked in code
for "finditer".  nobody has complained this far ;-)

isn't "iterfind" a better name, btw?  more like "iterkeys" (etc).

if nobody complains, I'll change the name, and check in some
documentation.

will have to think about scanner; I agree that it may seem to
be vaguely useful, but cannot think of a use case that isn't
better handled by findall/split/sub or iterfind.  can anyone?
