>Just make a log() function that takes a target (file, socket, etc
You'd need to find or store the socket everywhere where the function is used, which is cumbersome and leaks implementation detail in every client. A class allows to store this dependency (socket) internally. Another approach would be to create a lambda which stores the socket as a captured variable.
