 Let's look at which hints would need to be applied to the example interpreter
 from Figure \ref{fig:tlr-basic}. The basic thing needed to apply hints is a
 subclass of \texttt{JitDriver} that lists all the variables of the bytecode

 \texttt{4}. Therefore it is possible to constant-fold computations on them away,
 as long as the operations are side-effect free. Since strings are immutable in
 Python, it is possible to constant-fold the \texttt{strgetitem} operation. The
-\texttt{int\_add} operations can be folded anyway.
+\texttt{int\_add} are additions of constant \texttt{pc} and a true constant,
+so they can be folded away.
 
 With this optimization enabled, the trace looks as in Figure
 \ref{fig:trace-full}. Now a lot of the language interpreter is actually gone
