Sorry for the STRING_SWITCH proposal/noise. I was working on that in parallel with the templated version fixes. Now that I'm comparing the code gen of the two, I'm impressed with the optimizer generating essentially the STRING_SWITCH code gen. I'll keep the macro version in my back pocket in case I find a scenario where the optimizer fails to optimize the templated version code gen.
