The problem is it is clear Guido doesn't like functional programming -- his official statement is that "filter and map should die and be subsumed into list comprehensions". Yes, list comprehensions can do many of the things you can do with map/filter/reduce, but in a way where the functional idiom is obscured and one which is not easily converted to and from other languages.
