No, that only happens to functions stored in *class* attributes,
not instance attributes.

I'm just a function
Well, yes, that was a singleton class, so I kept data in the class
object. Now I can simplify the code by only keeping the instance
reference in the class, thank you. (Without knowing this, that bore no
visible benefits.)
