Do you still think that YAML is a good intermediate format choice? Do you think
an integration with other standard utilities to produce YAML would be possible
(prove, etc)?
YAML has a few ... issues. :/
I've laid them out before at http://cpanratings.perl.org/dist/YAML
Brian has said that the actual format is fine, but essentially the Perl
class sucks ass.
But eventually, you end up wanting a really nailed down file format, so
that you can use the data in a variety of applications, across a variety
of languages.
And XML was designed for, and still remains VERY good at, doing neutral
format data interchange.
