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?
