@dotnetCarpenter, are you suggesting that the data constructor's return type should be `Either String (StrMap a)` or `Either Error (StrMap a)` rather than `StrMap a`?

What do others think of these (breaking) changes? @Avaq? @Bradcomp? @masaeedu?

We have `swap :: Pair a b -> Pair b a` but not `swapEither :: Either a b -> Either b a`. Could you explain the relationship you see between...

That would be very cool indeed! It could even transform… ``` javascript // concat :: Semigroup a => a -> a -> a const concat = (x, y) => x...

That would be nice too. :)
