Please don't use Unicode quotes in code samples, that makes harder to try them.

What's this _ret thing?  Your completion function is overwriting a
global variable named "_ret".

Works for me in 'zsh -f' + 'autoload compinit; compinit' + (pasting your
code) + 'foo b<TAB>'.

I would make the first argument to _describe non-empty just in case
there's a null argument elision somewhere, but for clarity, it works for
me as posted.
