Not nice. Not nice at all.
Try reading:
{ "a" : this.b,
..... long object ....
"b" : 42,
..... more long object ....
}
Then try omitting the "b".
And then try
{"a" : this.b,
"b" : this.a }
Good luck debugging!
JSON literals, as currently designed, can't fail. They always describe
a value. All of these suggestions introduces ways to make syntax that
doesn't necessarily describe a value. In order to make a reference to
another object, you need two things to be in sync, either a tag/ref
pair or a path that must match the actual structure.
If you need cyclic structures or DAGs, perhaps JSON is not for you :)
