[Python-ideas] A better (simpler) approach to PEP 505

[Grégory Lielens]

Interesting, looking into, let's say, 100 of those is [not] None, randomly chosen, should give an very good idea of typical use for your code base.

I am curious about why you don't like solutions involving exceptions?
Performance?
Catching too much, like typing errors?
Less easy to distinguish between None and attr missing?
Less easy to combine None-aware and classic attr lookup on the same expression?
Something else?
