_D_e_s_c_r_i_p_t_i_o_n:

     Objects from class '"EmptyMethodsList"' are generated during
     method selection to indicate failed search (forcing backtracking).
     Other classes described here are used internally in method
     dispatch. All these are for internal use.

_U_s_a_g_e:

     ## class described below
     "EmptyMethodsList"

     ### Other, virtual classes used in method dispatch
     "OptionalMethods"
     "PossibleMethod"

_S_l_o_t_s:

     '_a_r_g_u_m_e_n_t': Object of class '"name"' the argument names being
          selected on.

     '_s_u_b_l_i_s_t': Object of class '"list"' (unused, and perhaps to be
          dropped in a later version.) 

_M_e_t_h_o_d_s:

     No methods defined with class '"EmptyMethodsList"' in the
     signature.

_S_e_e _A_l_s_o:

     Function 'MethodsListSelect' uses the objects; see
     'MethodsList-class' for the non-empty methods list objects.
