The absence of sets in early Python, the requirement to "import sets" when they first appeared, and the lack of a set syntax now all mean that people tend to avoid using sets and resort to lists, tuples, and "dicts of None" instead, even though they really want a set. Anywhere you see "if value in sequence:", they probably mean sequence is a set, and this code would run much faster if it really was, and might even avoid potential bugs because it would prevent duplicates... -- Donovan Baarda <abo at minkirri.apana.org.au> http://minkirri.apana.org.au/~abo/
