Checks for hasattr, which is considered harmful in Plone projects.
Python standard hasattr is considered harmful (within Plone projects).
The (hidden) problem with hasattr is that it swallows exceptions, which in your normal business logic you really don’t want to.
Specially in Plone context that could mean swallowing a database error, or a permission exception, etc.
Install with pip:
$ pip install flake8-plone-hasattr
