Has anyone suggested some sort of postfix macro syntax? I don't have one in mind, but perhaps there is some nice looking, viable one. That might have been a more general solution than a new operator.

Yes, numerous people. A few different discussions have gone by; it has many potential applications, but it introduces several aspects of syntactic weirdness and parsing weirdness, so it'd require a lot of care to introduce if at all.
