Right, Python has such poor control over side effects that it has not much chance of parallelizing stuff like list comprehensions in general. Maybe there's some chance of doing it for some special cases with RPython. See http://www.google.com/search?q="nested+data+parallelism"; for what's happening with some other languages. -- http://mail.python.org/mailman/listinfo/python-list
