Only one line more, if the following parses ...

spline
{ cubic_spline
  0, 0
  #declare Ind = 1;
  #while(Ind < 10)
    ,Ind, <Ind, Ind*Ind, 0>
    #declare Ind = Ind+1;
  #end
}


OK .. I(We all) know, what you mean, but probably this example was too simple
...

Question: How far back do we need Backward-compatibility ?
Commas are standard at least since 3.0, so I think somewhere should be a
hard-cut ...

_IF_ all the suggestions for the (somewhere in the far future) POV4 will
come true, we
will have a complete(?) different SDL, with hardly any way for
backward-compatibility ...
