_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.
