David, can ksh treat an invalid compound copy source, either not set
or not a compound variable name, as 'parameter not set'. i.e I want a
'parameter not set' in these cases:
1. copy: ksh -c 'set -o nounset ; compound a ; compound c=(
name="container1" ) ; a=c_not_set ; print -v a'
2. merge with +=: ksh -c 'set -o nounset ; compound a ; compound c=(
name="container1" ) ; a+=c_not_set ; print -v a'
3. copy with src gone: ksh -c 'set -o nounset ; compound a ; compound
c=( name="container1" ) ; nameref nc=c ; unset c; a=nc ; print -v a'
4. merge with src gone: ksh -c 'set -o nounset ; compound a ; compound
c=( name="container1" ) ; nameref nc=c ; unset c; a+=nc ; print -v a'
