  \begin{itemize}
    \item Everything within iterator must be parameterized.
      \begin{itemize}
        \item Generated code must be parameterized as well.
      \end{itemize}
    \item "Reconciliation", or re-updating the model on change.
      \begin{itemize}
        \item Consider hash-map-backed linked list implementations.
      \end{itemize}
