Subject: Parsing a CSV file column-wise

Is there a short-cut to parsing a CSV file column-wise using any of
the available Ruby CSV libraries ?

For example, at the moment I have:

 require 'csv'
 data = "1,2,3\n4,5,6\n7,8,9"
 CSV::parse(data)   # => [["1", "2", "3"], ["4", "5", "6"], ["7", "8",
"9"]]

But what I'd like is:

 CSV::parse(data,'columnwise')   # => [["1", "4", "7"], ["2", "5",
"8"], ["3", "6", "9"]]

Perhaps I just need to run the returned array through some kind of
transformation ?
