Hi Sven,

shouldn't it be set to #ignore by default for JSON then? Or is there a use case where it makes sense to have something else for JSON?

Herbert: I am not talking about (infinitely) recursive references, but referencing the same object, e.g.

Hi Peter,

Both cases will pass using this expression:

String streamContents: [ :out |
�� STON jsonWriter
�� referencePolicy: #ignore;
�� on: out;
�� nextPut: d ].

The problem is what to do with cycles.

Be faithful to what JSON.stringify does in JS. See attachment. :-)

Hi,

I don't think this should throw an error when I am producing JSON.

```
d := {
�� 'a' ->�� #().
�� 'b' ->�� #().
} asDictionary.

STON toJsonString: d.
```

dtto this

```
a := {'hm'}.

d := {
�� 'a' ->�� a.
�� 'b' ->�� a.
} asDictionary.

STON toJsonString: d.
```

Maybe I should forgo using STON>>toJson* out of laziness (it is preinstalled) and always go for NeoJSON?
