Unless variables and functions share the same namespace and syntax (as in the case of lvalue methods), functions are different in that they also encapsulate behavior. Variables merely encapsulate values.

      But what else is a tied variable but a variable hidden behind, and accessed by, several functions? It is just syntactic sugar (yes I am simplifying it a bit). Much of the same goes for overload, do something with a variable, and a function is called behind the scenes.

        Yeah, but the point is that variables can also encapsulate behaivor, and variables can also occupy a heirarchy of namespaces. So, a "global function" really isn't any better than a "global variable". They're both just globals.
