-\subsection{Let recursification}
-This transform makes all lets recursive.
-\subsection{Let simplification}
-This transform makes the result value of all let expressions a simple
-variable reference.
-\subsection{Let flattening}
-This transform turns two nested lets (\lam{let x = (let ... in ...) in
-...}) into a single let.
-\subsection{Simple let binding removal}
-This transforms inlines simple let bindings (\eg a = b).
-\subsection{Function inlining}
-This transform inlines let bindings of a funtion type. TODO: This should
-be generelized to anything that is non representable at runtime, or
-something like that.
-\subsection{Scrutinee simplification}
-This transform ensures that the scrutinee of a case expression is always
-a simple variable reference.
-\subsection{Case binder wildening}
-This transform replaces all binders of a each case alternative with a
-wild binder (\ie, one that is never referred to). This will possibly
-introduce a number of new "selector" case statements, that only select
-one element from an algebraic datatype and bind it to a variable.
-\subsection{Case value simplification}
-This transform simplifies the result value of each case alternative by
-binding the value in a let expression and replacing the value by a
-simple variable reference.
-\subsection{Case removal}
-This transform removes any case statements with a single alternative and
-only wild binders.
