What if we constructed the data.frame using from_csvfile? If I'm making
a df from vectors, I can do this as I create the df, but if I'm reading
it from a csv file, it seems harder. Unless you mean call it when you
get it out of the dataframe? This doesn't work either:
print [x for x in base.I(df.rx2('a'))] # same result
