Depending on your needs, you don't need to descend from TPersistent just
to get RTTI information in your classes. Simply wrap a TObject
descendant with {$M+} and deactivate the RTTI after the class definition.

For example:

  TtiVisited = class(TObject)
    ... define your class interface here...

Now TtiVisited will have RTTI information compiled in.
