What's wrong
If you add to __init__.py docstring and re-export, then the error WPS412 Found appears__init__.py `module with logic', which contradicts the documentation.
How to reproduce:
Make a project structure like this
├── package
│ ├── __init__.py
│ └── module.py
└──setup.cfg
Place in package/__init__.py some code
"""
Docstring for package.
"""
from package.module import make_foo as make_foo
For example, i put into package/module.py this code:
def make_foo():
"""foo func."""setup.cfg
[flake8]
# flake8 configuration:
# https://flake8.pycqa.org/en/latest/user/configuration.html
# We use `flake8` together with `ruff`, so we only select rules that
# are not ported to `ruff`.

select = WPS, E99
How it should be
There should be no WPS412 violation triggered.
