issue_comments: 165943594

Yes, my last comment wasn't clear. I think it's something to do with ChainMap - dict(series) gives the expected result, but dict(ChainMap(series)) throws an error (actually two...).

Potentially because list(series) gives values (but list(df) gives the keys)?

Regardless I'll add a note in the docs for DataFrame & Panel, and the Series can wait for the moment.

``` python In [30]: series=pd.Series(pd.np.random.rand(4))

In [31]: dict(series) Out[31]: {0: 0.26874240805523286, 1: 0.3110026841777368, 2: 0.22873881434409837, 3: 0.9946345046609677}
