I see a different behavior in master, and I know the edebug spec of
`cl-labels' had been changed recently.  Are you maybe able to try the
master behavior?

@Stefan: did you forget to mention the (FUNC EXP) binding definition
case in the docstring of `cl-labels'?

You are aware that `function' is a special form?


Michael.
