Re: Burning more bridges (mostly numeric ones)

lets not talk about this while people are buried with 7.8 release engineering, please :) there are certainly good ideas in Henning's (amazing) work, HOWEVER, one thing people often forget is that theres more than one valid computational formalization of a given mathematical concept (which itself can often have a multitude of equivalent definitions). and thats even ignoring the fact that the haddocks are full of readable Qualified names like "class Chttp://hackage.haskell.org/package/numeric-prelude-0.4.1/docs/Algebra-Algebr... a => C a where" :) On Fri, Mar 21, 2014 at 1:08 PM, Corey O'Connor wrote:

On #3: The library numeric-prelude achieves many of these goals (Plus a bunch more). If the experiences of using numeric-prelude are positive then using this or a subset of this as the standard numeric prelude might resolve these goals easily.

2. Move Semigroup into Prelude

2.1 Make Monoid depend on Semigroup.

NonEmpty seems to be frequently reimplemented, particularly by beginners. Including Semigroup in Prelude would save all this duplication.
