The one gotcha here is that for a SourceCodeKind of File we will set
__name__ in the generated code.  Instead creating the code like:

var code = Engine.CreateScriptSourceFromFile(filename,
                                  Encoding.Default,
                                  SourceCodeKind.Statements);

code.Execute(scope);

should result in __name__ not being overwritten.
