Because a unary negation node '~y' is more primitive than the corresponding difference node 'x~y', '~y' is easier to deal with while rewriting the tree. That's the main reason to add RevsetExpression::NotIn node. As we have a NotIn node, it makes sense to add an operator for that. This patch reuses '~' token, which I feel intuitive since the other set operators looks like bitwise ops. Another option is '!'. The unary '~' operator has the highest precedence among the set operators, but they are lower than the ranges. This might be counter intuitive, but useful because a prefix range ':x' can be negated without parens. Maybe we can remove the redundant infix operator 'x ~ y', but it isn't decided yet. |
