No. An "explicit" empty string would be '', "", or something like that. After `=' a value is expected but it's not there, so `[key]' is assigned the empty string. `typeset -A ary=(key)' is similar, the value is not there and the empty string is taken as the value instead. but in the case of typeset -A ary=([key]) it was historically an error > Irrelevant. See above
