Proposal: Add First and Last wrappers around Maybe to Data.Monoid

I've created http://hackage.haskell.org/trac/ghc/ticket/1189 to
suggest adding two Monoid instances around Maybe that, instead of
accumulating things like most monoids, just pick the first or last
piece of data they see.

Would a week (March 12) be enough time to discuss this?

Thanks,
Jeffrey Yasskin
