Re: fli:with-foreign-slots slots-and-options ... ?

OK, I've figured it out: each slot name can be a form that 
matches the lambda list

   (binding slot-name &key (:copy-foreign-object :error))

Which also allows you to rename unexported slot names from 
other packages.

It would be nice if the documentation for WITH-FOREIGN-SLOTS 
could be updated to reflect this.

Cheers,
