YAML defaults in Fixtures

DEFAULTS: &DEFAULTS created_on: <%= 3.weeks.ago.to_s(:db) %> first: name: Smurf *DEFAULTS second: name: Fraggle *DEFAULTS

When using that exact snippet, psych throws a parsing error. If one changes "*DEFAULTS" to "<<: *DEFAULTS", it works. Is the described syntax simply not supported yet? It seems to have been introduced in YAML 1.2<http://www.yaml.org/spec/1.2/spec.html#id2761803&gt; ...

What version of psych? I vaguely recall early versions of it rejecting stuff like that (that syck had previous accepted)
