-The |Agda.Compiler.MAlonzo.Compiler| module is responsible for transforming Agda treeless terms into Haskell expressions. In the primary function for this compilation, we introduced a new alternative that matches on terms with potential to be transformed into pattern lets. In order to be a suitable candidate for this optimisation, a |let| expression must exhibit the properties described in Section~\ref{sec:plet_logical}. Because these Agda terms used de Bruijn indexed variables, that means the case expression should be scrutinising the 0 (most recently bound) variable, and the requirements can thus be represented with a pattern matching expression |TLet _ (TCase 0 _ _ [TACon _ _ _])|, followed by a check that the default branch is unreachable.
