Many Haskellers are happy about this kind of stuff:

    min = head . sort

which is the very definition of a leaky abstraction. The blame lies with laziness, because it allows code to depend on implementation details of other code in crazy ways: "sort is O(n log n) unless you ask for only the first element, in which case it's O(n). What if you ask for the last element? Uhhh..."
