Note

For GNUC < 12 the run-time polymorphism built on std::variant with std::visit performs as badly, as one built with virtual inheritance. This header introduces a custom visit function, which deploys a templated if-else selection of the held alternative, which makes the variant-visit pattern performing faster.

The current implementation of the kf::visit accepts only one variant (TODO)
