#103 wontfix example from http://yaml.org/type/yaml.html fails to parse xi py4fun@…

Reported by py4fun@…, 6 years ago.

Description

example from  http://yaml.org/type/yaml.html fails to parse. Is it a wrong example ? (I have found already a few...)

>>> text = open('yaml.yaml').read()
>>> print text
# The following node should NOT be serialized this way.
encoded YAML node :
 !!yaml '!' : '!type'
 !!yaml '&' : 12
 !!value = : value
# The proper way to serialize the above node is as follows:
node : !type &12 value

>>> print yaml.load(text)
