• Well, it is a base class of itself, so there is nothing intrinsically wron with that

• Let's look at how _obs_get_parent_observers is used:

       126      push @observers, $class->_obs_get_observers_scoped,
       127                       $class->_obs_get_parent_observers;

• (That's the only place)

• At line 126 we have to include special code to include the observers of $class

• ... because at line 170 we included special code to omit them

• Conclusion: get rid of line 170 and we can _simplify)_ line 126
