Die zugrundeliegende Idee war gut, aber ich hab mich in einer <i>cleveren Implementierung</i>&#160;mit einem Lambda-Parameter festgefahren. Zwar brauche ich <i>nicht</i>&#160;die volle Generizit&#228;t und Quer-Beweglichkeit, aber der verallgemeinerte Enwurf f&#252;r ViewHook(ed) ist auch ohne das um L&#228;ngen besser als die bestehende Struktur

und zwar, genauer gesagt, eine Konsequenz der Entscheidung, nicht nur einen ViewHook, sondern ein ViewHooked zu machen. Ich hab die Beziehung in's Strukturelle hinen genommen. Damit mu&#223; auch die Wurzel diese Struktur unterst&#252;tzen, und damit wird an dieser Stelle die Abstraktion undicht.
