Pandas broadcast with numpy scalars

[tritemio]

Pandas objects (Series, DataFrame, etc...) can broadcast operations with python scalars. For example:

import pandas as pd
pd.DataFrame([1,2,3])*2

But when performing the same operation with a numpy scalar array:

import pandas as pd
import numpy as np
pd.DataFrame([1,2,3])*np.array(2)

pandas returns an error:

ValueError: Incompatible argument shape: ()

I can't find an explicit mention of scalar broadcasting in Pandas docs but this seems a natural case to be supported.
