      void apply(ArgumentStack stack) throws Throwable
      This method performs an invocation of this function object.

      Programmers should not call this method directly. Instead, for convenience, call this method indirectly via (F::apply List).

      Calling Convention from top to bottom (n >= 0):

      1. argument[n]
      2. argument[.]
      3. argument[2]
      4. argument[1]
      5. argument[0]

      The argument stack will be cleared and then the result will be pushed onto it. If the functor does not return a value, then the stack will remain empty.

      Parameters:
      stack - is a stack containing the arguments being passed to this functor.
      Throws:
      Throwable - in order to propagate exceptions thrown by the functor.
