As a huge user of boolean indexes, I have never expected this to work in
any way, shape or form. I don't think it works in matlab (but someone
should probably check that), so you wouldn't have to worry about converts
missing a feature from there. I have always been told that boolean indexing
will produce a flattened array, and I wouldn't want to be dealing with
magic when the array does not match up right.
Now, what if the boolean array is broadcastable (dimension-wise, not
length-wise)? I do see some uses there. Modulo that, my vote is to
deprecate.
