Any real-world use cases or compelling contrived examples?
ISTM, that the code calling it.stop() would already be in position to
break-out of the iteration directly or set a termination flag. Instead
of:
it = itertools.interruptable(iterable):
for x in it:
. . .
if cond(x):
it.stop()
Why not write:
for x in iterable:
. . .
if cond(x):
break
If needed, the for-loop can have an else-clause for any processing
needed in the event of interruption.
