WDYT of using the numbered enum pattern with NumberOfTypes as the last value?

E.g.,
enum AnimatedPropertyType {
  AnimatedUnknown = 0,
  AnimatedAngle = 1,
  ...
  NumberOfAnimatedPropertyTypes = 21
}

I added a NumberOfAnimatedPropertyTypes sentinel, but I did not explicit values,
because would just add (unneeded) redundancy.
