Hello,
The manpage of zshexpn states about "${=...}":
Note that splitting is applied to word in the assignment forms
of spec before the assignment to name is performed. This
affects the result of array assignments with the A flag.
but looks like the splitting isn't applied to word first:
% print -l ${=xx::=foo bar}
foo
bar
% print -l $xx
foo bar
%
I'm confused on this. Please help.
Thanks.

If you actually use the (A) flag,
% print -l ${=xx::=foo bar} . $xx . ${(A)=xx::=foo bar} . $xx
foo
bar
.
foo bar
.
foo
bar
.
foo
bar

OK thanks. I'll remember this only works with (A) flag.

I think we should say something like this about this feature in the man
page:
Note during assignments with the A flag, that splitting is applied to word
in the assignment forms of spec before the assignment to name is performed.
This will affects the result.
This sounds more clearly. Right?
