Re: Proposal: Add instances for Functor, Monad, Applicative to Data.Monoid.First, Last

This seems sensible, although I was for some reason sceptical at first, but I'm unable to articulate why and the proposal seems straightforward enough. So +1. Antoine On Wed, Jan 5, 2011 at 9:47 PM, Sterling Clover wrote:

Ticket: http://hackage.haskell.org/trac/ghc/ticket/4880

This proposal adds missing instances for the two newtype wrappers for Maybe in Data.Monoid. A patch is attached to the ticket. Both the motivation and implementation are straightforward.

Discussion period: 2 weeks (until 20 Jan 2011).

Cheers, Sterl
