Hi again,
Now I have some time, I'm trying to implement these MarkAsUsed method. 
However, I've got a big problem: I don't know where to find the location 
most of the times. For example, in generation/Typer3.n (line 789)

      def rewrite (expr : TExpr) {
        | TryFinally (body, handler) =>
          def fld = clo_type.DefineAndReturn (<[ decl:
            mutable $(Macros.NewSymbol ("finally_needed") : name) : bool;
          ]>) :> IField;
          fld.HasBeenAssigned = true;
          fld.HasBeenUsed = true;
          def fldref = TExpr.FieldMember (InternalType.Boolean, thisref, 
fld);

How can I know where the reference is located so I can call the 
MarkAsUsed (IMember, Location) method?

Thanks in advance,
Alejandro Serrano "Serras"
