Re: Maximum and Minimum monoids

I agree that it's more correct to leave them as semigroups. The real path should be to move the semigroup package into the platform for the next release. (And, eventually, subsequent to that, to remove First and Last from Data.Monoid entirely). Cheers, Gershom On 12/27/12 7:13 PM, Herbert Valerio Riedel wrote:

Can't you use Option (Max a) from the semigroups package? This was my first thought as well; IMHO, the elementary Minimum/Maximum operation forms a semigroup rather than a monoid.
