Hi, I'm trying to setup a YAML file using YAML::XS, now, for the most part it's fine if I use a standard YAML format, but, I'd like to include defaults and aliases, but, whenever I load a "defaulted" block it's in a << hash first.

#!/usr/bin/env perl

use Data::Dumper;
use YAML::XS;

my $config = LoadFile('config.yml')->{'production'};

print Dumper($config);
[download]

defaults: &defaults
  src:
    host: localhost
    database: db
    username: root
    password:
  nfs: /tmp

development:
  <<: *defaults

test:
  <<: *defaults

production:
  <<: *defaults
  nfs: ian
[download]

I'd also ideally like to be able to override the defaults. If my block looks like this:

production:
  src:
    host: localhost
    database: db
    username: root
    password:
  nfs: /tmp
[download]

All is well and fine. Any tips gratefully received, the alias stuff comes from a ruby background.
