Even if there were such syntax, it'd be questionable whether "typeset -p" should employ it, because that would increase the bash/ksh dissonance and could not be used with "readonly" or "export" in the case where POSIX_BUILTINS is set. Come to think of it, separating this from POSIX_BUILTINS as I did, may have already reduced (or rather, failed to improve) POSIX compatibility for those two commands.
