Hm. What makes you think it's not being used widely enough? I suppose
JSON is more popular, but it's not like YAML is dying. AFAIK there's a
3rd party yaml parser that we could incorporate with its authors'
permission -- this would save people from a pretty common dependency
(just like we did for JSON).

i think ruby created its own reality here: yaml wasn’t popular because it wasn’t in the stdlib, and became popular as soon as it was. its advantages as arguably most human-writable serialization format helped here. at least that’s my interpretation.
