ByteArra# plus those primitives was the only way to have unboxed arrays with fast access starting with 6.6, ForeignArray access is no-op, so we can just use obvious Ptr operations (via Storable class) to get unboxed arrays fast access. so, no more need for those special ByteArray# access operations but Array library still old, so any effort based on its spources, got the same restrictions also, ByteArray# may be unpinned, but afaik, this isn't really important - it can be coerced to Ptr for the period of one operation -- Best regards, Bulat mailto:bulat.zigans...@gmail.com _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
