Why "remove" them? Instead, we have these things called "comprehensions" (which, now that I say that, seems a rather odd name), and you can control whether they result in a list or a generator with () or []. I don't see why they need to be "removed". Lists are already a special case of the "only one way to do it" principle ([] vs. list()), and pragmatically I don't see any reason to remove them here; it doesn't add comprehensibility, leaving them in doesn't significantly affect the mental size of the code (the *comprehension* is the hard part, the final form should be relatively simple), it's not worth breaking that code. -- http://mail.python.org/mailman/listinfo/python-list
