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 :-)
