At least commas are necessary in parts of function parser. Below example does
not work without commas.

#local Params=2;

#local F=array[5];

#local F[0]=function(a){0};
#local F[1]=function(a,b){0};
#local F[2]=function(a,b,c){0};
#local F[3]=function(a,b,c,d){0};
#local F[4]=function(a,b,c,d,e){0};

#macro Do(c)
  //#if(c>0),#end  /* <-- uncomment this line to make it working */
  c
#end

#local f=F[Params-1];
#local my_f=function{f(#local C=0;#while(C<Params)Do(C)#local C=C+1;#end)};
