        Parameters
        ----------
        msg : raw message send by the kernel containing an `user_expressions`
                and having a 'silent_exec_callback' kind.

        Notes
        -----
        This function will look for a `callback` associated with the
        corresponding message id. Association has been made by
        `_silent_exec_callback`. `callback` is then called with the `repr()`
        of the value of corresponding `user_expressions` as argument.
        `callback` is then removed from the known list so that any message
        coming again with the same id won't trigger it.
