87,Add a varient of unfoldrN,tommd,,"I suggest we either add a variant of unfoldrN or make an API-breaking change to the current one.  The variant (placeholder name for now) would have a signature:

    unfoldrN' :: Storable a => Int -> (b -> Maybe (a, b)) -> b -> (Vector a,b)

In otherwords, we provide the resulting type `b` after applying the function N time (or fewer, if it returns Nothing).",enhancement,new,major,,,,,
