[PyYAML] problems with nested mappings

-----BEGIN PGP SIGNED MESSAGE-----

Hi.

I don't understand why this script:

## BEGIN
from yaml import add_constructor, load, __version__


def test_constructor(loader, node):
    kwargs = loader.construct_mapping(node)
    print kwargs
    return kwargs
add_constructor(u'!test', test_constructor)


sample = """
bar: !test
  a: b
  foo:
    x: 1
"""


print __version__
print load(sample)
## END

Produce, as output:

  3.10
  {'a': 'b', 'foo': {}}
  {'bar': {'a': 'b', 'foo': {'x': 1}}}

I was expecting:

  3.10
  {'a': 'b', 'foo': {'x': 1}}
  {'bar': {'a': 'b', 'foo': {'x': 1}}}



Thanks  Manlio Perillo
