Grim C++ Tales from the Crypt: The Visitor Pattern (2017)

Your code won't compile because interactor::interact is not defined on the base class. That line is needed because the overload resolution is static. So with the macro ACCEPTS, you build the code where the overload is resolved.

I see. There is no interact signature that accepts IThingy, which is the whole point of this pattern. Thanks.
