Is there any way to define constants in prolog? I'd like to write something like list1 :- [1, 2, 3]. list2 :- [4, 5, 6]. predicate(L) :- append(list1, list2, L). The work-around I'm using now is list1([1, 2, 3]). list2([4, 5, 6]). predicate(L) :- list1(L1), list2(L2), append(L1, L2, L). but it's a bit clumsy to bind a "useless" variable like this every time I need to access the constant. Another (even uglier) work around I suppose, would be to include cpp in the build-chain. (In my actual application, the list is a large LUT used in many places.)
