The example code the author comes up with: https://github.com/dpugson/examples/blob/master/chpt1_the_visitor_pattern/example.cpp https://github.com/dpugson/examples/blob/master/chpt1_the_vi... Which implements the pseudocode: https://cppcrypt.tumblr.com/post/168134402897 https://cppcrypt.tumblr.com/post/168134402897 main { thingies = [ purpleThingy, littleThingy ] interactions = [ commentOn, cherish ] for (interaction in interactions) for (thing in thingies) interaction.interact(thing) } The author does mention things like "function pointers can be used in simple cases" and "std::variant would avoid the need to overload the method". But the main reason for having the C++ code the way it is is because "you can't dispatch to overloaded methods at runtime". https://cppcrypt.tumblr.com/post/169439207562 https://cppcrypt.tumblr.com/post/169439207562 ff.
