I like it. At my previous job, I extended std.json with an array 
index operator just to end up replacing it with a variadic getter 
to get around the problem of incomplete paths. Like that, there 
are some ways to get around this sort of issue, but I wouldn't 
complain about having it right out of the box.

Perhaps there should also be a ?[] operator.

foo?["a"]?[0]?["llama"]
