and type classes. once i've forget to addinline pragma, my program
(serializing arrays) becomes 200x slower. it was due to use of
hieararchy of several type classes. afaiu, their dictionaries are also
lazily evaluated plus we have usual overhead of haskell closures that
are ready for particular application
