While it's a little strange the semantics are that it returns an array
which is empty if there's no error. The implementation is something
like this:
ree-1.8.7-2011.03 :003 > h = Hash.new {|h, k| h[k] = []}
=> {}
ree-1.8.7-2011.03 :004 > h[:huh]
=> []
ree-1.8.7-2011.03 :005 > h
=> {:huh=>[]}
Which is why you see what you see.
