There was a long thread about this on python-dev that might be worth going back over, where I had the same misconception (that functions should always return the same type as their arguments).  While I think that should be the default design, it isn't always the best API.  (The real rule, if I recall correctly, is that functions should never accept *mixed* argument types for input data.)
