What it does#
Checks for assignments with multiple or non-name targets in stub files.
Why is this bad?#
In general, stub files should be thought of as "data files" for a type checker, and are not intended to be executed. As such, it's useful to enforce that only a subset of Python syntax is allowed in a stub file, to ensure that everything in the stub is unambiguous for the type checker.
The need to perform multi-assignment, or assignment to a non-name target, likely indicates a misunderstanding of how stub files are intended to be used.
