Feature Request: Is there any possible to read other props in a specific validator function?

As above, I want to validate a props data propA in the validator function and I want to read the props data propB so that I can judge whether they are valid together.

@JounQin As @LinusBorg has said, the feature for prop validation depending on other props is too complex, error-prone (needs correct prop initialization order), not commonly needed, and cannot solve the problem of interdependent validation (propA requires propB, propB require propA). On the other hand, it’s already easy enough to be implemented with computed properties. So in my opinion this feature shouldn’t be included in vue since it’s too user-specific.

Therefore my recommendations remain to be a). use computed properties. b). use a mixin to check inside hooks.

@fnlctrl your solution is just like validating them together on the created() hook, but I think we should do the validation in a proper place rather than mixing it in our business logic.
