That's the comma operator. I didn't know you could overload it! That's pretty crazy. However, I have never seen anyone do that. Do you have any real world examples?
See e.g. the very-popular Eigen library, in which the type CommaInitializer basically exists for the sole purpose of overloading `operator,`, allowing a cleaner matrix initialization syntax.
