I think I'm missing something. Daniel wants a `list.get` method with
similar semantics to `dict.get`. So instead of writing:
```
try:
x = lst[i]
except IndexError:
x = default
```
one could write `x = lst.get(i, default)`. How would you rewrite that with
PEP 505?
I've also wanted this a couple of times, although I can't remember the
reason. It's not just about traversing incomplete nested data structures. I
don't see much disadvantage since the analogy with `dict.get` would make it
very easy to learn and understand, to the point that I've wondered why this
doesn't exist already.
