Adding the implicit call-stack more than doubles the length of the type
signature! This might seem like a silly complaint, but I think there's a
real cognitive overhead there, especially when you consider that Prelude
will be one of the first modules that novices might read the haddocks
for.

Well, scaring beginners away from partial functions may be not that bad of an idea ;)
