std::function will allocate on every call of take_and_do_error_handling (at least with libstdc++ as in this implementation std::function's small buffer can only fit two pointers but most of the time, the lambdas will contain 3 pointers). This impose multiple heap allocations (and deallocations) on every callback.
This comes with the cost of increased binary size. But I suppose it's worth it as this change also enables better/easier inling and avoids indirect function calls through the std::function machinery.
