r59 claims to "Remove y/n from the boolean constants." However 'n|N' is not removed from the corresponding regexp. BTW: why was it removed? Looking at  http://yaml.org/type/bool.html one would expect it to be there.

With the latest PyYAML (3.04):

I think this is a bug - at least it should raise a yaml.scanner.ScannerError?, like yaml.load("'") does, and then it can be easily catched as a malformed stream. Right now, it's hard to deal with this.

Thanks, Iustin

quote from the documentation:

>>> class Monster(yaml.YAMLObject):
...     yaml_tag = u'!Monster'
...     def __init__(self, name, hp, ac, attacks):
...         self.name = name
...         self.hp = hp
...         self.ac = ac
...         self.attacks = attacks
...     def __repr__(self):
...         return "%s(name=%r, hp=%r, ac=%r, attacks=%r)" % (
...             self.__class__.__name__, self.name, self.hp, self.ac, self.attacks)

>>> yaml.load("""
... --- !Monster
... name: Cave spider
... hp: [2,6]    # 2d6
... ac: 16
... attacks: [BITE, HURT]
... """)

the thing is, yaml.load ignores the __init__ method of the Monster class. it doesn't even matter if it's there at all. in yaml.load you can specify aditional variables and they get added to the object. intended behaviour?
