Subject: Hash hidden in hash with default object

I observed this odd behavior when setting a hash to have as its default
value another hash which itself has a default value set:

>> hash_in_hash = Hash.new(Hash.new([]))
=> {}
>> hash_in_hash[:a][:b] << :incognito
=> [:incognito]
>> hash_in_hash
=> {}
>> hash_in_hash[:a]
=> {}
>> hash_in_hash.keys
=> []
>> hash_in_hash[:a][:b]
=> [:incognito]
>> hash_in_hash[:a].keys
=> []

?
