Review comment:
TIL:
https://docs.python.org/3/tutorial/classes.html#class-definition-syntax
> In practice, the statements inside a class definition will usually be
function definitions, but other statements are allowed, and sometimes useful —
we’ll come back to this later. The function definitions inside a class normally
have a peculiar form of argument list, dictated by the calling conventions for
methods — again, this is explained later.
Perfecly legitimate use case IMHO :D ..
