Something like this was discussed at one point; I believe people referred to it as `reswitch`.

In general, you're not going to get very far by naming a bunch of features and asking if we should have them. Show us motivating examples. Help us understand what you want them for. (And if you don't know why you'd want them, well, why are you proposing them?)
