ยท Absorb it into the vector package, which is currently its only client (we think).
We definitely need a library like primitive to share code among other libraries. I think that package might as well be primitive. To my knowledge there are at least three, nearly-identical wrappers of the GHC array primops: one primitive (used by vector), one in text, and one in unordered-containers. The reason that these libraries cannot use the array or bytestring libraries as wrappers over Array# and ByteArray# is that design trade-offs made in these two libraries are not always what you want: * Arrays are too big and use a (relatively) inefficient indexing scheme. * ByteStrings are too big and also have a somewhat inefficient indexing schemes. They're also pinned. -- Johan
