Re: [Yaml-core] YAML-RPC

Hello Brian!

I'll let Steve address the other items, but from what I 
know he's not going to be able to do any further work on
PyYaml for a wee bit.  I'm sure you are welcome to "hack"
it some... support for explicit transfers could be much
better, etc.

Steve originally had to_yaml for the method name.   I think
that __yaml__ is entirely appropriate:

  - It is quite magical and is othogonal to application
    concerns.  It's not any where near a "normal" function.

  - It follows the same pattern as __str__, __iter__, and __repr__ 
    that is, it returns an object which complies with the appropriate
    protocol.

  - It won't have a name clash.  YAML is big enough now that no one
    would be using __yaml__ for anything.  Eventually yaml may even
    get popular enough to be included in the Python core, and in this
    case __yaml__ will be entirely appropriate.

So, overall, I think that __yaml__ is the best route and I've
thought about this quite hard.  As for the protocol for __yaml__,
now that's something that needs some deep thought.  It really
needs to expect a tuple (type-family, value) instead of just
a value for starters.  Ideally the value would be an iterator.

Best,

Clark
