Any function can do anything. I can write a function called "read_from_file()" that doesn't read any files.

Amazing, I know.

Also please actually read the comment before replying:

The point the OP made was that operator overloading is not nice - it means that any operator (not just function) can do anything. It makes code harder to read and reason about.
