Hi Edward, I started @telling you on #haskell, but it has become too long for that. :) The following functions would be nice additions to Data.List.NonEmpty in the semigroups package: replicate1p :: Whole n => n -> a -> NonEmpty a take1p :: Whole n => n -> NonEmpty a -> NonEmpty a splitAt1p :: Whole n => n -> NonEmpty a -> (NonEmpty a, [a]) Also, your warnings in the haddocks about blowing up on negative arguments don't seem to be needed for take, drop, and splitAt. We could avoid the problem with negative arguments for (!!) too by providing an alternative for Whole numbers. But in that case the function would still be partial, so I'm not sure if it's worth it. I wish there were some way to get Whole to default to Natural. Thanks, Yitz
