If I had a scenario where I needed a function that would change its
behavior based on its attributes I would use an object instead. If I
really, really needed it to behave like a function, then I would
override __call__.

Using a function's attributes to modify its behavior seems like using
a singleton or a module variable to modify the behavior of functions.
I would avoid it if I wanted to write code that someone else
(including myself) may want to use one day. Otherwise, it would be
hard to keep different bits of code separate from one another.
