C.hier: discussion on alternative implementations of run-time polimorphism is missing. #1225

Open imre-palik opened 6 years ago

imre-palik commented 6 years ago

There is a long section on the rules of implementing run-time polimorphism via class hierarchies, but no guidelines on the alternative implementations on runtime-polimorphism, (I.e., with std::variant, or type erased containers).

I think some guidance on when to use which sollution would also be great. (I am addicted to variants these days, so I cannot really come up with those ...)

Perhaps add a cross-reference to the guidelines where variant and type erasure are discussed?
