TaggedList is unnecessary for data.frames

[flying-sheep]

see here

>>> a = np.array([('a', 1), ('b', 2)], dtype=[('h1', '<U1'), ('h2', '<i4')])
>>> a['h1']
array(['a', 'b'], dtype='<U1')
>>> a[a.dtype.names[0]]
array(['a', 'b'], dtype='<U1')
>>> a[0]
('a', 1)

and if we really need easy indexing by col number, this class is better in every respect (performance, versatility, …)

Hi,
sorry for the very late reply, this message just slipped through.
You are right, the TaggedList class is just a stupid helper class because I didn't find anything appropriate (without putting too much research into it, to be honest ...)
What I definitely want to avoid is a dependency to any other major package just for the sake of replacing this class, which is why I'm not too keen to borough anything from the pydata project in the moment.
