      Replace current definitions by " [...] and MUST result in values of a primitive type whose values are totally ordered.".

      Description

      Definitions in section 3.2 and 3.6 state that the second parameter must result in a primitive numeric value. This is too restrictive, actually it is only required that there is a total ordering on these values.

      Consider, for example, getting the latest stock by product: $apply=groupby((Product),topcount(1,Date))
