The result is the following Stratego module: module Exp imports list-cons option signature constructors Minus : Exp * Exp -> Exp Plus : Exp * Exp -> Exp Mod : Exp * Exp -> Exp Div : Exp * Exp -> Exp Mul : Exp * Exp -> Exp Int : IntConst -> Exp Var : Id -> Exp : String -> IntConst : String -> Id This Stratego module can be imported in you Stratego transformation tool.
