Then something is strange in your environment.

The (f) forces splitting on lines, resulting in an array, and is
assigned inside APPS=( ... ).

Similarly for the = (which uses $IFS to split).

I've just confirmed with "zsh -f" that this works just fine with default
options.  I suspect that you missed the outer ${(f) ... } wrapper.
