Issue with apispec.LazyDict, recursion limit reached

[soluwalana]

>>> from apispec.lazy_dict import LazyDict
>>> x = LazyDict()
>>> x[1] = lambda: 203
>>> import ujson
>>> ujson.dumps(x)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: Maximum recursion level reached

Not sure if I should leave this as a bug here or in apispec.

Thanks for the report.

I expect this has been fixed in UltraJSON 2.0 by 53f85b1:

Removed generic serialization of objects/iterables

The behavior of ujson has always been to try to serialize all objects in
any way possible. This has been quite a deviation from other json
libraries, including Pythons standard json module, and the source of a
lot of confusion and bugs. Removing this quirk moves ultrajson closer to
the expected behavior.

Instead of trying to coerce serialization ultrajson will now throw a
TypeError: "repr(obj) is not JSON serializable" exception.

Please could you retest with the latest release?
