I proposed adding some extra columns with flags showing different aspects
of safety of a particular entry.  I didn't propose any "safety"
benchmarks.

I actually would like to be able to submit 1 entry with bounds-checking on
and 1 entry with bounds-checking off.  I also think it would be very
interesting to see some of the entries from other languages ran with
safety disabled/enabled to see the difference in performance between the
two modes.

You are acessing your array with an int index or the equivalent, right?
Then it is a safety issue because you are *assuming* that the array index
has not overflowed.
