Python goes to great extents to reduce these sorts of errors in other
parts of the language. You'll notice that none of the old Python
programmers have argued that this change would be un-pythonic. Some of
them like the feature too much to give it up for safety but nobody
questions the goal of improving language safety. If you compare Python
to Perl you'll find that Python *is* a B&D language -- in comparison
(but is much less of one than Java). That's balance is a major virtue.
