BTW, that was *deliberately* written that way as a compromise
between efficiency and template bloat. It can of course be
done like

   void print(alias SEP=" ", alias EOL="\n", A...)(A a) {
      mixin(`write(`~iota(A.length).map!(a=>"a["~text(a)~"],")().join("SEP,")~"EOL);");
   }

but that seems too expensive, when the use is just in toy
programs and debugging.
