why is this ? return is the perl yield. the only difference is that the "exhausted" situation is on your own. so basically:def count_from(x): while True: yield x x = x + 1 naturals = count_from(0) print(next(naturals)) print(next(naturals)) print(next(naturals)) print(next(naturals)) is written in perl use experimental 'signatures'; use feature 'say'; sub count_from ($x) { sub { $x++ } } sub NEXT ($generator) { $generator->() } my $naturals = count_from 0; say NEXT $naturals; say NEXT $naturals; say NEXT $naturals; say NEXT $naturals;

* the python community was unfair comparing the langages (using ugly perl code and nice python counterparts). instead of taking time to explain all the biases, perl community repetedly asserted that the authors of those article were incompetents and gone away.
Not sure about anyone else, but comparing the Python vs Perl example you gave above, I would still say Python is the nicer-looking language.
