    Sorry for my bad writing, I didn't mention:
    the parameter type == the return value type

    My intention is:
    parameter type of atomic readq/writeq == parameter type of non-atomic
    readq/writeq
    &&
    return value type of atomic readq/writeq == return value type of
    non-atomic readq/writeq

    # == means "should be equal"
