The sanity checks would be more interesting if they were correct. You are assuming $_ is set and modified in place, which holds true only for a subset of the solutions.

Try changing the order in which you run the benchmarks, and you'd see that $_ will be the same after my solutions run as before, no matter who else's ran immediately beforehand. Perhaps you should check actual return values of subs which return values.
