A common solution is to allow an extra comma at the end of lists, so you 
could do:

> #declare Spline =
>  spline
>  { cubic_spline
>    #declare Ind = 0;
>    #while(Ind < Amount)
>      Ind/(Amount-1), Point[Ind],
>      #declare Ind = Ind+1;
>    #end
>  };

I know C allows this in some cases and it's very convenient. (Maybe POV-Ray 
does too, but my point is that it works well when commas are required, which 
is good for avoiding problems like steven's.)
