Subject: Hash.new(Hash.new) doesn't use Hash.new as default value

Hi -

In the documentation for the 'new' method in the Hash class in Programming
Ruby it says that 'anObject' will be used as default value, but consider the
following example:

var = Hash.new(Hash.new)
var['index1'] = 'value1'
var['index2']['index22'] = 'value22'
var['index3']['index32'] = 'value32'
var['index4'] = 'value4'
p var['donotexist']

Why does "p var['donotexist']" output {"index32" => "value32", "index22" =>
"value22"} - and _not_ just {} (a new Hash)?
If it's no bug, I think it's a bug in documentation. - and not a very logic
behavior.
