convention for unused variables

[Clara Benac Earle]

Something related to what you want to do here is what they do with 
"refactoring" where the idea is "/changing the structure of a program 
without changing its semantics/."

refactoring Haskell. At the moment we have submitted a proposal for 
refactoring Erlang, so let's hope it is successful! :-)
