Pandas alias for slice(None)

Having bunch of slice(None) in multilevel indexes (>=3 levels) looks pretty unreadable.

Does it make sense to have an alias, maybe pd.any?

For example in numpy the np.newaxis is alias for None:

Have you checked out pd.IndexSlice?

this is fully documented here: http://pandas.pydata.org/pandas-docs/stable/advanced.html#using-slicers

I was not aware about IndexSlice! Thanks for the tip.
