That isn't actually too hard. You'll want to write your own defop__ dealie, but essentially you can just pull the vars you want out of the req variable. before calling the rest of the body.
No, it is. Because the problem is that there's a whole bunch of defop_ dealies. defopr, defop-raw. Sure, you can make a macro-making macro, but I think it's better if we start from the top and define it in defop-raw, so that everything that builds on top of it uses (arg1 arg2) syntax.
Of course, there might be subtleties involved here anyway.
