Incidentally:

% typeset x
% typeset -p x
typeset x=''
% x+=(a b)
% typeset -p x
typeset -a x=( '' a b )

This has been the case for as long as += has been around, as far as I
can tell.  Works this way even with typesettounset, but not if the
parameter was never declared or has been explicitly removed with
"unset".
