The transposing seems to be almost an unimportant implementation detail because the user is asking for the data to be split up by columns. Personally, I think that this should be transparent to the user and should be able to work -- although I am not exactly sure if one should just simply return a list of numpy arrays with the column names dropped, or a list of one-column record arrays.
Well, easy enough to output a list of arrays for each column, be they of the same dtype or with different ones.

Not needed. The unpack argument is used as the very end of the function anyway.
Anyhow, could you open a ticket to that effect (else I'm quite likely to forget about it).

Mind opening a second a ticket ?
