As I pointed out in the original patch, maybe there was a confusion on my part where I assumed we would have a three valued enum, but the direction actually would make it four valued, and these would be controlling the suppression of the keyword in orthogonal places.

Can you clarify?

I don't mind bool vs two valued enum, if that's your preference, but the tying up of two separate conditions into one variable is making the other patch look awkward.
