[Yaml-core] YAML for config files

[Brian I. <in...@tt...>]

Hi fellas,

I've been thinking over the use case of YAML for config files. Our
current format is optimal for most data serialization and data dumping.
But for config files, I might be a little adverse towards adopting YAML,
if I didn't happen to be one its primary founders. It's not a hard sell
per se, but it's not a slam dunk either.

Here is what I would want out of YAML for configs:

1) No YAML header.
2) The ability to throw away blank lines.
3) More lax indentation rules
 A) 2, 3 or 4 space indentation
 B) Tab to nearest eight
 C) Varying indentation within a document.

Here are the things in YAML that aren't really needed for config:
1) YAML Header 
2) Multi-line string
3) Properties: (explicit transfer, alias, anchor)

---

So I've been thinking if we should reserve a headerless YAML document
for such a use case. It's really the only time where requiring a header
would be a bad thing.

I just wanted to throw this out for discussion.

Cheers, Brian
