The mopp package also exports the function SLOT-DEFINITION-DOCUMENTATION which while not strictly part of the MOP really should be and is implementened on most systems.
It surprises me slightly that you think that SLOT-DEFINITION-DOCUMENTATION shouldn't be a generic function.
on openmcl and lispworks it is. on other lisps it's a wrapper around a generic function, what's to be gained?
You could be slightly nicer to other implementations by doing ... (unless (provide-mopp-symbol sym (or #+openmcl :openmcl #+sbcl :sbcl #+cmu :cmu #+lispworks :lispworks :unimplemented)) (warn ...)) and either provide a method on :unimplemented or a method on NO-APPLICABLE-METHOD.
good idea.
Unless there's a reason not to, you should be using the "SB-MOP" package here. (If there is a reason, sbcl-devel wants to know about it!)
the symbol metaobject exists in sb-pcl (though it does not name a class), it doesn't exist in sb-mop. [hence the Cc to sbcl-devel].
