I mean you'd have to write a function to implement the operations you
want. It isn't as convenient as a pre-defined special-purpose
expansion. It would have to be something to stick in an rcfile or
other library. The unstable ksh has `typeset -c` for object copy (like
typeset -m in the last stable version).
