void andOrList(SqlWriter writer, SqlKind sepKind) {
  SqlBinaryOperator sepOp =
      sepKind == SqlKind.AND
          ? SqlStdOperatorTable.AND
          : SqlStdOperatorTable.OR;
  for (int i = 0; i < list.size(); i++) {
    SqlNode node = list.get(i);
    writer.sep(sepKind.name(), false);

    // The precedence pulling on the LHS of a node is the
    // right-precedence of the separator operator, except at the start
    // of the list; similarly for the RHS of a node. If the operator
    // has left precedence 4 and right precedence 5, the precedences
    // in a 3-node list will look as follows:
    //   0 <- node1 -> 4  5 <- node2 -> 4  5 <- node3 -> 0
    int lprec = (i == 0) ? 0 : sepOp.getRightPrec();
    int rprec = (i == (list.size() - 1)) ? 0 : sepOp.getLeftPrec();
    node.unparse(writer, lprec, rprec);
