Each of both approaches do have its own advantages and drawbacks.


It seems, I need to repeat myself: the post you quoted explicitly said 
it does not care about the name of the dunder attribute. So, pick one 
appropriate, like "__to_be_assigned_lhs_name__", which should not clash 
with most usecases.


Furthermore, the same argument could be used against all dunder names.
