Bug discovered by @FBruzzesi #3194 (comment) Now I need to fix 200/222 failures 😂
mypy really doesn't like any variation of this
(https://docs.python.org/3/reference/datamodel.html#object.__slots__) > If a class defines a slot also defined in a base class, the instance variable defined by the base class slot is inaccessible (except by retrieving its descriptor directly from the base class). > This renders the meaning of the program undefined. > In the future, a check may be added to prevent this.
Mostly just moving repeat globals/builtins lookups into locals
