+/**
+ * Intraprozedurale Analyse zur Abschätzung der Aufrufrelation. Es wird
+ * die Menge der instantiierten Klassen bestimmt, und daraus eine Abschätzung
+ * der aufgerufenen Methoden.
+ *
+ * Voraussetzung ist, dass das Programm keine Methodenzeiger handhaben kann.
+ * In diesem Fall koennten Methoden verloren gehen.  Oder wir muessen nach
+ * allen "freien" Methoden suchen (siehe cgana).
+ *
+ * @@@ Die Analyse sollte wissen, von welchen Klassen Instanzen ausserhalb
+ * der Uebersetzungseinheit alloziert werden koennen.  Diese muessen in
+ * die initiale Menge allozierter Klassen aufgenommern werden.
+ *
+ * Nach: David F. Bacon and Peter F. Sweeney,
+ *       Fast static analysis of C++ virtual function calls
