I recall my discovery from beta testing times when lack of commas still is
parsed fine but behaves wrong:

  Well, if you think "#if(whatever) , #end" is less obfuscated than "(-Foo)",
then be my guest.

In some cases, it can be. Usually, I'll use the other method...a single 
entry outside the loop.

Maybe a parameter list structure could eventually be added to the macro 
language...you would just append entries to the list, and ignore the 
comma issue entirely.

#declare ParamList = param_list {< 1, 2, 3>, < 4, 5, 6>}

ParamList.append_value(< 1, 3, 5>);

polygon {ParamList.count
    ParamList
}

Or for the original example:

#declare ParamList = param_list

#declare Blah = 80;
#while(Blah > 0)
    ParamList.append_value(dSpline(Blah));
    #declare Blah = Blah - 1;
#end

polygon {ParamList.count
    ParamList
}

This is the wrong group for this question.  This group is for discussion of
the POV-Ray source code.  General questions about using the POV-Ray scene
description language should be asked in either povray.general or
povray.newusers.
