My issue with is is that if you ask for a key in an object

associative arrays in the language and probably more correct.
Yes, this is what I meant with the JavaScript part of API. In
addition to opIndex(), there should of course also be a
.get(key, default_value) style accessor and the "in" operator.
There is a parallel discussion about the concept of associative
ranges:

Maybe you could also have a look there, because JSON seems to be
a good candidate for an associative range.
