Sometime they are necessary, to avoid circular import problems
(but this not a problem with Haskell).
...in theory. In practice GHC needs help with circular imports, and
some cycles might be impossible to resolve.
This is interesting.
Where can I find some examples?

The "impossible to resolve" is my interpretation of a discussion on
the lists several months ago.
I don't see any mention in RWH offhand.
