 \subsection{Alternative syntax}
 Because of these typing issues, misusing Haskell's do notation is probably not
 the best solution here. However, it does show that using fairly simple

       As noted above, when using nested (hierarchical) states, the state types
       of the \quote{upper} functions (those that call other functions, which
