Albeit the idea was to be branch less in the function that is a bottleneck,
you are right, I threw something like this together (buggy, it will crash
on an unknown symbol) albeit it compiled the test that on the other hand
did indeed not help at all, even very slightly slower (likely due to
initialization time of the dummy variables)
