   I think we can write the scalar function for users calling into compute directly.  I agree it would be somewhat meaningless today if applied in, for example, a project expression.
   
   Can we have it take a starting value as one of the function options?
   
   Then we can use this whenever we get around to implementing the feature in the execution engine.
