>Please consider escape hatches differently from basic stuff like head and you see we argue for the same end result. Head is plain bad, should be removed or annotated as the smelly thing it is. maybeHead and non-empty-collections are the way fwd there, would you agree? I don't get what you're trying to say. I never said that head was good. The discussion about head is a sidetrack to the original question, which is "To what extend can we do without [partial functions]?", and to which my answer is "we can't do without". head is not a good example of a partial function, and its existence doesn't conflict with the idea that good partial functions are a necessary part of the language.
