In order to infer what an argument represents, call :meth:`infer_argument` with the corresponding function node and the argument name. :param callcontext: An instance of :class:`astroid.context.CallContext`, that holds the arguments for the call site. :param argument_context_map: Additional contexts per node, passed in from :attr:`astroid.context.Context.extra_context` :param context: An instance of :class:`astroid.context.Context`.
