[Haskell-cafe] ANNOUNCE: SubHask-0.1

SubHask is an alternative prelude for programming in subcategories of Hask. The documentation includes examples on: * the category of polynomials * how to give set a monad instance in two different categories * basic linear algebra using the category of linear functions More information at: http://github.com/mikeizbicki/subhask I'd like to emphasize that SubHask still has a number of bugs that need to be fixed. This release should be seen as just a technology preview.
