Well, not in the:

$ ./Src/zsh -c 'f() { typeset -n ref=var; local var=1; echo $ref; }; var=0; f'
0

Which IMO is better than 

$ bash -c 'f() { typeset -n ref=var; local var=1; echo $ref; }; var=0; f'
1
$ mksh -c 'f() { typeset -n ref=var; local var=1; echo $ref; }; var=0; f'
1

But is IMO somewhat inconsistent with:

$ ./Src/zsh -c 'f() { nameref ref=var; local var=1; echo $ref; }; f'
1
