I was poking around with this idea to see what ksh93 does, and it's not all
that consistent. Consider the difference in behavior between these two
cases. This one throws an error:
typeset -n foo ; typeset -i foo=7*6 ; typeset -p foo
and this one throws away the nameref attribute:
typeset -n foo ; typeset -i foo ; foo=7*6 ; typeset -p foo
