-This uses Java's conditional-assign syntax along with the ''asVariadicOp()'' helper, which returns an ''Expr.Variadic'' instance if the given expression is a jlist of the given type:
-<code java>
-  private Expr.Variadic asVariadicOp(Token op, Expr expr) {
-    return
-      expr instanceof Expr.Variadic vExpr && vExpr.operator.type == op.type
-      ? vExpr : null;
