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:<br>
<br>
1. There are often multiple sensible generalizations of a Prelude function.<br>
<br>
2. You have to add more type annotations since types cannot be infered from the functions.<br>
<br>
<br>
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!<br>

I should change my vote to:<br>
