That depends a lot on your pattern of usage.
In many cases, the compiler can eliminate checks by "proving" to itself
that they can never fail. Or it may hoist checks outside loops.
I would suggest that you ignore your intuition, and only try to fix
things once you have measured and know for a fact that the index checks
are a problem.
