\section{Primer on CESK}

\begin{frame}
  \frametitle{What is a CESK machine?}

  \begin{itemize}[<+->]
    \item Abstract machine for interpreters, introduced by Matthias Felleisen.
    \item Stands for $C$ontrol, $E$nvironment, $S$tore, $K$ontinuation.
    \item Based on Matt Might's blog post on CESK machines \cite{might-cesk}.
  \end{itemize}
\end{frame}

\begin{frame}
  \frametitle{What are each of the components?}

  \begin{itemize}[<+->]
    \item $C$ontrol is your current term.
    \item $E$nvironment is a list of addresses.
    \item $S$tore is a mapping of addresses to values.
    \item $K$ont is what gets evaluated next.
  \end{itemize}
