What it does#
Checks that instance method
self arguments have type annotations.
Why is this bad?#
Type annotations are a good way to document the types of function arguments. They also help catch bugs, when used alongside a type checker, by ensuring that the types of any provided arguments match expectation.
Note that many type checkers will infer the type of
self automatically, so this
annotation is not strictly necessary.
