Comment (by wyager):

 > Remember that the prime motivation for Storable is the FFI

 That's a fair argument. But I'm curious; how often do people use the
 various `Storable` array types?  I use `Data.Vector.Storable` a fair
 amount, and if that's a common use case, it makes sense to support it as
 well.

 Which is precisely what I've done here, although I think it could make
 sense to use a standardized, agreed-upon representation known to be
 alignment-safe and have good performance.

 That said, I think you're right that this would be equally well-served by
 a library external to `base`, so on that note I'll close the ticket.
