http://hackage.haskell.org/trac/haskell-prime/wiki/Underscore I think it is basically the wrong idea to encode (type and) usage information in the name of an identifier. One should use the type system for that, or, failing that, annotations. Something like data Foo = Foo | @SuppressWarnings("unused") Bar See my proposal for unified and extendible annotations http://www.haskell.org//pipermail/haskell-prime/2006-February/000279.html http://java.sun.com/docs/books/tutorial/java/javaOO/annotations.html Of course compilers/IDEs are free to support whatever naming conventions they want but I think such conventions should not go into the language standard.
