There are other ways for the function signature to be visible. Concepts can be used (requires C+20) but the implementation needs to remain in the header file. On the other hand if one wants to put the function implementation in .cpp and does not need to store the passed callable but only to call it, it may be better to use something like function_ref/function_view which will allow the base function to be called with different callable types - std::function, lambdas, function pointers, etc without needing to construct std::function object just to call it inside the function. example The implementation of the function_view was taken from here and adapted slightly.
