[...] Ok, one minor thing. If you just extend a pad you need to know the actual nesting depth. The vtable function elements returns this information, but there is ATM no operation in core.ops which calls it. If you allow a negativ argument to new_pad, meaning to copy from 0 to depth+$1 inclusive, this would make the common case of just extending the scope more easy. I attached a cascading patch (because its easier to review)
