Yes, the point is that it's something that you can check for by
examining the class in question without having to examine any other

You have to treat builtin functions as part of the language. Of
course Python has this situation where someone could rebind the name
"len" to some other function, so you have to deal with that too, maybe
just at the file scope. An OOP approach (lst.len() instead of
len(lst)) that binds the builtin names to datatypes might be
preferable in some situations but I'll leave that one for the

I don't see how pylint could know which instances to flag, without
doing type inference on all the objects to know that the variable
belonged to an instance of some other class.
