Re: Proposal: Make Semigroup as a superclass of Monoid

Well, it seems the consensus is high enough that we'll try to go ahead with this. As it affects the Prelude, we may put out another poll / wider broadcast just to avoid any appearance of ambushing folks with another change to the Prelude without announcement, but I think at this point my intent is to pick a path to make this happen. -Edward On Wed, Apr 29, 2015 at 8:51 AM, Stephen Tetley wrote:

The consensus seems largely to favour the high level proposal to add a Semigroup class, but there hasn't been much discussion of the implementation details i.e. what to do about mappend or a Semigroup-like candidate (problematic for empty lists, of course).

So what's the conclusion on this? We seem to have a strong consensus on going ahead with the proposal, and a weaker consensus for doing so via the long path.
