The main annoyance with the total versions is that the existing fromJust has the wrong convention.

Oh well. Consistency is overrated.

So you don't mind the breaking change in the `either` package? For the lazy; `either` defines:

Data.Either.Combinators.fromLeft :: a -> Either a b -> a Data.Either.Combinators.fromLeft' :: Either a b -> a (~Right similarly)

Also, packages `MissingH` and `extra` define the consistent

fromLeft :: Either a b -> a

(don't know if user numbers of those count as significant in any way.) -1 on both partial and inconsistent total
