 In Scala, we represent the AST as a tree-form object. The tree has different types of nodes, each one representing a different programming structure. The types of nodes are of course represented as different classes, which all inherit from a class called Tree. Conveniently enough, the classes correspond pretty much one-to-one to the rules of the BNF grammar given in the language specification. E.g. in the language spec we read that a module looks as follows:
 
- //ModuleDef// ::= **program** //Identifier// **extends** **App** **{** ( //ClassOrFunDef// )* //Expr//? **}**
+ModuleDef ::= **program** Identifier **extends** **App** **{** ( ClassOrFunDef )* Expr? **}**
 
 and indeed in the implementation we find a class 
 
-''  case class ModuleDef(name: Identifier, defs: List[ClassOrFunDef], optExpr: Option[Expr]) extends Definition''
+`case class ModuleDef(name: Identifier, defs: List[ClassOrFunDef], optExpr: Option[Expr]) extends Definition`
 
 You can find the source code of the AST [[http://lara.epfl.ch/~gschmid/clp20/SymbolicTreeModule.scala|here]].
 Note: This is not exactly the code we will use in later assignments, but it's good enough to serve as a reference while implementing this first assignment.

 You will have to complete the interpreter by implementing the missing methods (marked with the placeholder ''???'').
