Subject: Rio/CVS tells me: undefined method '>'

Rio with CVS didn't work as expected on my data, so I tried the examples
given at <http://rio.rubyforge.org/classes/RIO/Doc/INTRO.html>

I ran into the same problem. What's wrong? Does this work for anybody
else? 

| $ irb
| irb(main):001:0> require 'rio'
| => true
| irb(main):002:0> rio('f.csv').puts!(["h0,h1","f0,f1"])
| => #<Rio:0x3ff2d5ac:"path:f.csv" (Stream::Reset)>
| irb(main):003:0>  rio('f.csv').csv.records[]
| => [["h0", "h1"], ["f0", "f1"]]
| irb(main):004:0> rio('f.csv').csv[0] > rio('out').csv
| NoMethodError: undefined method `>' for [["h0", "h1"]]:Array
|         from (irb):4

The following works correctly, though:

  rio('f.csv').csv > rio('out').csv

Updating rio didn't help me. I'm at ruby 1.8.6 and rio 0.4.1 on cygwin.
I'll try to repeat on my FreeBSD server ... actually got around to
fixing the broken Ruby there and got the same response for rio, so it's
not a cygwin thing.
