Webfunction overhead. std::function can cause significant overhead. Because std::function has [value semantics] [1], it must copy or move the given callable into itself. But since it can take callables of an arbitrary type, it will frequently have to allocate memory dynamically to do this. Some function implementations have so-called "small object ...

For a general overview of std::variant and what it can do, have a look at ... ms thang meaning
