We don't enable this flag precisely because we end up needing to scatter
const all over the place like confetti. I'm not convinced that use of const
improves code quality. I fear we'd end up with 'const foo * const bar' all
over the place -- ugly and confusing to most programmers (who frequently
mess up const placement, in my experience).
