Operators that only vary by case would be... confusing. I'm not super keen on the other syntax (either the ?? or .? operators) but I do think they read well in C# where they come from. Different things work in different languages, some times.

What about a new keyword: default

So you'd write the above examples like this:

default hi = len(a)  # Only executes the assignment if the left-hand is None

default encoding = sys.getdefaultencoding()

I would think `||` would be much better.

It could be a kind of "semantic or" which could use the aforementioned dunder has_value.

-1, though, but to the general None-awareness.
