I'd suggest not killing each other over this argument.  What would be
useful to me and I guess most outsiders eyeballing YAML, is if it
worked like JSON but with less superflous " garbage and the nice block
array and hash support.  There's even one JSON parser/emitter out
there that departs from standard just to allow optional quotes for key
names.

I had a look at the YAML2 wiki sounds like eyaml is the idea what to
call this code feature set.  I don't know about the two tiers above
this cyaml and syaml seems like one might be enough but it probably
doesn't matter too much since probably 90% of users want eyaml.  If
you do have three levels defined what's to argue about put complex
keys in syaml and be done with it.

Incidentally I don't like tabs and liked original decision to avoid
them.  eyaml supposed to be bare bones right
