An  ocaml  defunctorizer, developped  by  Julien  Signoles,  is to  be
released soon.  Using it,  you'll get an  equivalent code  without any
functor anymore. I guess it'll ease your paranoia...

Moreover,  the first  benchmarks with  this defunctorizer  proved that
using  many functors  does  not  have necessarily  a  (bad) impact  on
performance. So you can really stop being paranoid :-)
