Das ist recht einfach (nicht sehr nützlich), hilft uns aber dabei, uns auf die Funktionsweise der Unterabhängigkeiten zu konzentrieren.

## Zweite Abhängigkeit, „Dependable“ und „Dependant“ { #second-dependency-dependable-and-dependant }

Dann können Sie eine weitere Abhängigkeitsfunktion (ein „Dependable“) erstellen, die gleichzeitig eine eigene Abhängigkeit deklariert (also auch ein „Dependant“ ist):
