surprisingly, deepseq is not used as much as I thought.
http://packdeps.haskellers.com/reverse/deepseq lists a lot of packages,
but (after grepping through some of the code) most just define NFData
instances and/or use it in tests, but rarely in the „real“ code. For
some reason I expected it to be in more widespread use.

But therefore I am even more interested in non-hackaged applications
that I can be allowed to stud – in return I might be able to tell you
way to speed up your application.
