This also required adding a loop guard in case clone panics Add specialization for copy There is a better version for copy, so I've added specialization for that function and hopefully that should speed it up even more. Switch FromIter<slice::Iter> to use `to_vec` Test different unrolling version for to_vec Revert to impl From benchmarking, it appears this version is faster
