Changes (by mechvel at botik.ru):

  * difficulty:  Unknown => Moderate (1 day)
  * keywords:  => cyclic import

Comment:

 The bug is easy to find. 18 .hs modules, each value (except 1 small
 function) is
 trivially defined as (\ _ _ ... -> error ""). Its complexity is only in
 many imported types
 and many imported values, with a bit of cyclic import.
