assigning list to series with boolean indexing

[stefsmeets]

Whenever a boolean array is used to assign some list or array to another series, it returns "ValueError: Length of replacements must equal series length". This was working fine in pandas 10.0, but broke with 10.1

import pandas as pd
import numpy as np
x = pd.Series(np.arange(10))
sel = x < 5
len(x[sel])
x[sel] = range(5) # doesn't work anymore
x[0:5] = range(5) # works

#3236 will close this, thought I had testing this in #2745 but apparently not

thanks for the report

@Tarlitz this is merged into master, pls try out

@jreback Runs like a charm over my entire code, thx! :)

@Tarlitz good to here..

@Tarlitz also...I would recommend you put the rhs side as a Series in any event (and map the indicies to your values), or a full length ndarray, which reduces the chance that your boolean mask is not 'lined up' with the rhs, just my 2c

@jreback Thanks for the tip, I'll keep that in mind!
