I beg your pardon, but what's wrong with writing {\xxx{aa}}^2
if you want to preserve the braces? See attached file.
This is a problem with semantics. IMO, \xxx{aa}^2 defines aa as the
nucleus, whereas {\xxx{aa}}^2 explicitly says that \xxx{aa} is the
nucleus. The fact that \xxx{aa}^2 works in TeX is unfortunate.
