bug with empty df?

[Neal Becker]

In [3]: from pandas import DataFrame, Series

In [4]: 

In [5]: df = DataFrame (np.zeros ((0,0)))

In [6]: df

Out[6]: 

Empty DataFrame

Columns: []

Index: []

In [7]: df.iloc[0] = Series (np.ones (4))

In [8]: df

Out[8]: 

Shouldn't this assignment have thrown an error?

[Jeff]

In master this is correct

In [12]: df.iloc[0] = Series(np.ones(4))

IndexError: iloc cannot enlarge its target object

In [13]: df.loc[0] = Series(np.ones(4))

ValueError: cannot set a frame with no defined columns
