Subject: Why such math-expression error?

Hi
I've got in a script a code:

(( ${+ice[make]} )) && ...

It causes the following error:

=E2=88=9Ezinit-make-hook:9: bad math expression: operand expected at end of=
 string

When I do local -A ice, the error disappears. Printing ${(t)ice} shows
empty string, and unset ice doesn't help.

Why such error? In interactive shell, I can $+ basically any expression I
want in an $((, specifically (( ${+unset_var[string]} )) works fine.
