As of right now, qdoc generates warnings about the copy/move constructor, assignment/move operators, and (in)equality operators for classes that have them implicitly defined, but explicitly documented, such as QMap.

If qdoc is able to discover that those special member functions exist, then it could generate the documentation automatically, taking "\ingroup shared" into account.

If qdoc cannot discover this, then we need to be able to silence the warning.
