Comment :  
Adds missing functionality used by Rails:

- yaml\_as method, which is basically a declarative alias to  
tag\_class().
- quick\_emit method, which allows to emit yaml nodes.

Looks good. Did you confirm that a return from the block passed to  
quick\_emit does not get passed back to the caller?

Yes, while this is terribly underspecified, I confirmed that quick\_emit  
returns string YAML representation of the user-emitted YAML nodes. The  
major use for this is to override to\_yaml method in order to provide  
custom YAML representation for a type.
