-1, for the reasons given by Henning. If we're going to be changing stuff in Prelude, why not start with Functor/Monad? On Thu, May 16, 2013 at 5:04 AM, Henning Thielemann < lemming@henning-thielemann.de> wrote:

It is certainly a kind of beginner module, but that's good. Experts know how to import. Putting the most general functions into Prelude does not work because:
1. There are often multiple sensible generalizations of a Prelude function.
2. You have to add more type annotations since types cannot be infered from the functions.
There is simply no need to change Prelude and all packages that rely on specific types. Just don't be lazy and import the stuff you need!
I should change my vote to:
-10
