Hi,<div><br></div><div>Here&#39;s my problem :</div><div>- I have the class NSCollectionStream which define ( for example ) �#atEnd</div><div>- I have the class NSSubclassOfCollectionStream ( which is a suclass of NSCollectionStream).</div>

<div><br></div><div>When I use a trait in NSSubclassOfCollectionStream that required the method #atEnd, the defintion in NSCollectionStream is not used and the method #atEnd is overridden with :</div><div>�� � � atEnd</div>

<div>�� � � � � self explicitRequirement.</div><div><br></div><div>I think we should take care about definitions in superclass, no?</div><div><br></div>
