This solves just the '__len__' issue. But if do the slice operation like
this

        self.context.list_field[offset:limit]
        
I get the following error

        ForbiddenAttribute: ('__getslice__',[...])
        
I guess my approach is flawed. Implementing all the functionality (like
the one I did for length) that a list provides is a overkill. So, please
guide me in this regard.

Thanks
