Class definition with collections

Class definitions can have collections and these can have strings e.g.:
  class Url(namedtuple('Url', url_attrs)):
and this results in:
  warning: Detected potential recursive class relation between class conda::_vendor::urllib3::util::url::Url and base class Url!

Strings are now possible and seen as strings.
