Re: less verbose Python lib

Hello Nico,

in Python YAML is typically mapped directly to the trees of objects.
The YAML sequence is mapped to the Python list, so using

    yaml.dump(['eggs', 'bread', 'milk'], default_flow_style=False)

and if the equivalent output of '[eggs, bread, milk]' is acceptable,
the keyword argument may also be omitted. Unless you need to
explicitly deal with the representation and serialization steps, it's
the easiest way to deal with YAML in Python.

Good luck,
Dennis.
