The implementation avoids amend-in-place for integer indices in case of index error. Perhaps performance could be improved by pre-verifying the indices, and if none are out of range, then doing the amend in place? This would save memory, and the CPU usage should be about the same (index bounds checking needs to be done in either case; this new way requires accessing the data one extra time, but would avoid one data copy, so it should come out around even). -- Mark D.
