As a potential stepping stone towards possible future changes in the default
behaviour here, what if itertools were to offer an opt-in "check_signals(itr,
*, iterations=100_000)" helper function that was essentially a more efficient
version of::
def check_signals(itr, *iterations=100_000):
while True:
next_slice = islice(itr, iterations)
for count, item in enumerate(next_slice, 1):
yield item
if count < iterations:
raise StopIteration
This would:
1. Provide a straightforward way for folks to explicitly opt-in to periodic
signal checks
2. Provide a way to check for potential compatibility issues with other
libraries and components to better assess the risks of switching the default
behaviour
