I don't think we have something for that right now. Maybe you can try something like: (eval-when-compile (defclass dummy () ((SLOT)))) Better would be to wrap this into an `eieio-declare-slot` macro (which could later be replaced by something which doesn't end up defining a class as a side-effect).
