Comment (by barry.wardell):
My benchmarks uncovered a problem. It turns that the speed of a standard BSSN evolution is badly affected by this change. I think this is partially because there are extra partial derivatives which computed independently of whether they are actually used by a specific branch of the IfThen. I'll have a closer look at exactly what extra is computed after the changes and see if this can be optimised.
