Solve the following python programming problem given the following code:
@ staticmethod 
def specialize(args, gtl_map, loop_id) : 
    "Given ``args``, instances of some :class:`fusion.Arg` superclass,
        create and return specialized :class:`fusion.Arg` objects.

        :param args: either a single :class:`host.Arg` object or an iterator
                     (accepted: list, tuple) of :class:`host.Arg` objects.
        :gtl_map: a dict associating global maps' names to local maps' c_names.
        :param loop_id: indicates the position of the args` loop in the loop
                        chain
        " 
    def convert(arg, gtl_map, loop_id) : 
        maps = as_tuple (arg.map, Map) 
        c_local_maps = ([None] * len (maps)) 
        for (i, map) in enumerate (maps) : 
            c_local_maps [i] = ([None] * len (map)) 
            for (j, m) in enumerate (map) : 
                c_local_maps [i] [j] = gtl_map [('%s%d_%d' % (m.name, i, j))] 
_arg = Arg (arg.data, arg.map, arg.idx, arg.access, arg._flatten) 
        _arg._loop_position = loop_id 
        _arg.position = arg.position 
        _arg.indirect_position = arg.indirect_position 
        _arg._c_local_maps = c_local_maps 
        return _arg 
try : 
        return [convert (arg, gtl_map, arg) for arg in args] 
except TypeError : 
        return convert (args, gtl_map, loop_id) 

    
    

    Fix the buggy line: return [convert (arg, gtl_map, arg) for arg in args]
