Note that we have added common binary operators like \CI{Lt} that did not exist
in the grammar of \autoref{sec:intro:while}. These operators could also be
constructed from other boolean expressions. We have also added \CI{Div} for
-integer division. It is a useful addition in this example, as it will force us
-to implement error handling in the evaluation of arithmetic expressions when we

+integer division.
As an example, the example program from \autoref{sec:intro:while} would be
stored in the AST as follows:
