Are python's generators / yield possible in perl?

[Nomen Nescio]

Does perl have an equivalent to python's generators? I want
to be able to basically call yield() instead of return() to implement
iterators. If this exists, can XS code access it via perl guts?

It might be better to explain what you want to do than assume we know
Python.

Alright, I've looked them up, and to answer your question, not in
perl5. There is a module on cpan called coroutine0, but it is extremely
ugly.

Incidentally, it took me all of five minutes to look up Python's
generators, find a link to perl coroutines, and then Google for perl
coroutines and find that they're to be implemented in Perl6, though a
few people have had a go at implementing them as modules in Perl5.
Perhaps you should do a little research next time?

Although you might not get exactly what you want, Mark Jason's
Higher Order Perl will get you most of the way there.
