Upgrade that doesn't need extendedglob (#e needs it):

% var=abc
% echo ${${${(M)var:#abc}:+ternary1}:-ternary2}
ternary1
% var=abcd
% echo ${${${(M)var:#abc}:+ternary1}:-ternary2}
ternary2

Substituted :# for # and (#e). :# wants whole string, so no #e needed. Maybe this is what Bart was aiming at in previous topic.
