    # These sequence methods are duplicates of number or mapping methods.
    # For example, in the C API, "add" can be implemented either by sq_concat,
    # or by np_add.  Python will try both. The opcode mapping is identical
    # between the two. So e.g. the implementation of the BINARY_SUBSCR opcode in
    # Python/ceval.c will try both sq_item and mp_subscript, which is why this
    # opcode appears twice in our list.
