Hi
I've got in a script a code:
(( ${+ice[make]} )) && ...
It causes the following error:
∞zinit-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.
