1)
typeset -T oset=(
typeset -A s
function add {
nameref var=${.sh.name}
typeset elem
for elem; do
: ${var.s[$elem]:=0}
done
}
)
oset foo bar
foo.add a b
bar.add d e
print "${foo.s[*]} : ${!foo.s[*]} \n${bar.s[*]} : ${!bar.s[*]}"
gives:
0 0 0 0 : a b d e
0 0 0 0 : a b d e
as though s is being shared.
2)
typeset -T olist=(
typeset -a l
)
olist foo
foo.l[1]=x
print "${!foo.l[*]}"
gives:
0 1
(A spurious '0' index is created)
3)
typeset -T oset=( typeset -A foo )
oset bar
bar.foo=( [a]=b [c]=d )
print ${!bar[*]}
gives:
0
4)
(typeset -T foo=( integer i ) )
typeset -T foo=( integer i )
gives:
typeset: foo: type cannot be redefined
despite the first typeset nominally being done in a subshell.
