[eclipse-clp-users] two simple queries

Can someone explain why the query

   make2([r(6,[e8,e10,e19]), r(5,[e18,e15])]).

behaves as expected, whereas the query

   make3([r(6,[e8,e10,e19]), r(5,[e18,e15])]).

doesn't?  The param() in make3 is not necessary, but seems 
to cause a problem.


make2(Rs) :-
         (foreach(r(I,Path), Rs) do
              write(I), write(' '), writeln(Path)
         ).

make3(Rs) :-
         (foreach(r(I,Path), Rs), param(I,Path) do
             write(I), write(' '), writeln(Path)
         ).

Thanks.
