Starting on goal: Prolog$Goal(car=l("[]", "say", Prolog$Var(id=0L, instance=r3)))
Goal arity 2: "[]"(say, $x)
nextSolution
  Goal: "[]"(say, $x). Got clause: "[]"(say, _1) :- "[]"(user, says, "[]"(_2, "*", _3, "*", _4)); "[]"(_1, "=", intmul, "()"("[]"(_2, ",", _3, ",", _4)))
  Clause unifies to: "[]"(say, $x) :- "[]"(user, says, "[]"(_2, "*", _3, "*", _4)); "[]"($x, "=", intmul, "()"("[]"(_2, ",", _3, ",", _4)))
  gdash: "[]"(user, says, "[]"(_2, "*", _3, "*", _4)); "[]"($x, "=", intmul, "()"("[]"(_2, ",", _3, ",", _4)))
Goal arity 3: "[]"(user, says, "[]"(_2, "*", _3, "*", _4))
New goal: "[]"(user, says, "[]"(_2, "*", _3, "*", _4)); "[]"($x, "=", intmul, "()"("[]"(_2, ",", _3, ",", _4)))

Done with goal!
