"on" or "off" as node name becomes "True" or "False"

[s.p.helma@…]

When loading a yaml document with node names "on" or "off" (or similar) the node names are stored as "True" or "False" in the dictionary:

>>> y = """
---
value: 3.14
on: 1
off: 2
"""
>>> yaml.safe_load(y)
{False: 2, True: 1, 'value': 3.1400000000000001}
>>> yaml.load(y)
{False: 2, True: 1, 'value': 3.1400000000000001}

IMHO this rewriting makes sense for the value, but not for the node name.
