the derived result type of f was not essentially unique: f :: .. -> (.T, .a)

  [o u[11651944]:a -> u[11651944]:a]  -> c[11210672]:c
but st_attr_vars was
  [c[11210672], c[11210672]]
(u[11651944] is missing)

  class c m :: *(m Int) -> (m Int)
is not accepted anymore

U is unique but instantiates class variable x that is non uniquely used.

fromString is not yet supported
some error handling improved
parial instances are temporary disabled

2. bugfix for fusion algorithm

ignored the type specification. Now he treats f as a function, and hence
gives a type error

Start = f
  where
    f :: String
    f = 1
