Virtual dispatch how?
You mean a different class for each enum value? (instead of a common class with a function ptr argument)
This is what we will have in the next change.
I just wanted to separate the refactor that changes a lot of files but has no behavior change (this cl), from the improvement that changes only this file and speeds up runtime.
