Our V2 doesn't *quite* match, since V2 requires the two fields to have the same type, but I agree. =) On Thu, Oct 18, 2012 at 2:36 PM, Anthony Cowley <acowley@seas.upenn.edu>wrote:

I am +1 for this proposal, but only as long as these instances are not exported by the Prelude. They are useful when you know you want them but will confuse newbies -- based on evidence from #haskell, where lambdabot has such instances in scope.
Please no orphan instances - I think a pair type that supports
arithmetics
deserves a custom type.
Agreed. Another -1 on the proposal from me.
I am also with Henning, and a -1 for the proposal. If it's too confusing to export by default, then the instance belongs to a less general type. There are appropriate types that have the desired behavior all over hackage. I am currently partial to V2 from the linear package.
