set object is not JSON serializable with iterable_mode=IM_ANY_ITERABLE

[gdub]

>>> rapidjson.dumps({1}, iterable_mode=rapidjson.IM_ANY_ITERABLE)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: {1} is not JSON serializable

>>> rapidjson.__version__
'1.8'

Given that documentation states "any iterable will be dumped as a JSON array," I would expect a set object to serialize to an array.

Note, it does appear that creating an iterator object from the set will successfully serialize:

>>> rapidjson.dumps(iter({1}), iterable_mode=rapidjson.IM_ANY_ITERABLE)
'[1]'

Thank you for the report, I will try to understand and fix the issue.

I'm not sure if/how this should be fixed...
On one hand, I realize that IM_ANY_ITERABLE (that by the way is the default for iterable_mode) suggests that it should slurp anything for which iter(X) works, but under the hood it is actually implemented as PyIter_Check(), and thus it is currently misleading.
On the other hand, I'm reluctant to effectively rectify its implementation, because that could break existing usages: doing that for example breaks three tests, this to mention one.
I will think about this, or wait for some feedback 😜

I started hacking on this, but got distracted away, sorry. I will try to refocus, as time permits.
