v0.2.7

Fixed

• Do not treat a class's own attribute as a dependency on a same-named outer definition.
  An enum member or class variable named like the module constant that aliases it (for
  example CACHE_MISS = _Sentinel.CACHE_MISS beside class _Sentinel(Enum): CACHE_MISS = auto()) previously forged a false class -> constant edge that
  closed a cycle with the real constant -> class edge, hoisting the constant
  above the class it references and raising NameError at import. A name bound in a
  class's own body is now recognized as belonging to that class's namespace and imposes
  no ordering on outer definitions.
