DataEx.hs as other such code of mine has been written in the hope it
might be useful, or at least instructive. I usually place such code in
the public domain, and I wish DataEx.hs and the related code in the
Haskell-Cafe message to be in the public domain as well. Please use
the code as you wish. If a specific formal statement from me is
required, please let me know.
