When we call `json.dumps` on a non JSON serializable object, we obtain an error:

```
TypeError: 4 is not JSON serializable
```

Here, 4 was actually a `numpy.int64` object and not a native int. But it is not explicit in the error message. We should mention the type of the object as well:

```
TypeError: 4 of type numpy.int64 is not JSON serializable
```

This already changed in issue26623 and issue24641.

Python 3.5 now gets only security fixes.
