If I do:

a=Series([1,2,3],index=['a','b','c'],name='x')
b=DataFrame(a)

I would expect b to have a single column 'x' with indices a,b,c; instead only a.values is retained.

I noticed that the series index is still ignored, and the resulting dataframe has a default index. Is this a specific design decision?
