Or both? The scanner interface seems vaguely useful as a low-level tool to create other higher-level variants; but the finditer() call seems to nicely capture a common case.

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?
