\begin{document}
\section{Generics sind notwendig}
Generics können nicht ignoriert werden.
Folgender Fall ist Typisierbar:
\begin{program}
<T> T m1(T x){
return m2(x);
}
m2(x){
m1(1);
m2("Test");
return m1(x);
}
\end{program}
Beim weglassen des Generics T wäre es aber nicht mehr möglich.
Dann erhält jeder Constraint, welcher in Verbindung mit der Methode m1 steht
den selben TPH.
