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
Actually the fact that they may be unpinned is really important for small allocations like short strings. Pinned allocations are slow and lead to heap fragmentation. Duncan
