Unlike v0.4 for now, I opted not to use TagMap.forEach for these loops.
That was done because the inner classes of v05 make the change a bit messier.

forEach would still be preferable, since it faster and incurs less allocation for OptimizedTagMap. I will likely revisit this in a future PR.

But for now, these changes make v0.5 on par or better than v0.4 in load tests.

I prefer not to introduce synthetic accessors, so I tend to make things package visible.
