YAML is nice until you accidentally change indentation.  Then the game 
is over.  Having bolluxed up many fortran codes in my (distant past), I 
have to say "just say no" to things *requiring* indentation.  In YAML's 
case, it suffers from the same problem with Python (yeah, I am gonna get 
some nasty dirty emails now).  Structure by indentation is IMO *evil*. 
I have heard that GvR actually agrees with this, though that is 3rd 
order hearsay.

JSON is a little more intelligent.  Easier to parse.

I guess, as a person who uses Perl quite a bit, I have to smile when I 
hear about some folks in some other language somewhere forming a team to 
write a parser or validator for some XML they are banging their heads 
on.  I am spoiled by Perl's (extraordinarily) powerful tools for stuff 
like this.

Darn ... I hope I didn't just light off a language war ... (ducks, 
covers, and runs)
