There are, but the test in question only distinguishes set/not, there
traditionally has not been a test for whether declared.

The issue at hand (well, one of them) is that zsh treats

    declare var
as 
    declare var=

so you get different results from

    declare var
    [[ -v var ]]

in different shells.
