For example, the lambda term |(\x y -> x)| can be constructed as follows:
\begin{code}
phoasExample :: Phoas v (x -> y -> x)
phoasExample = PLam (\x -> PLam (\y -> x))
phoasExample = PLam (\x -> PLam (\y -> PVar x))
\end{code}
An attractive property of parametric \hoas{} is that we use Haskell binding to construct syntax, and that terms of type |(forall v. Phoas v a)| are always well-scoped \cite{phoas}.
