I guess I should have given the version in my original post:

$ irb -v
irb 0.9(02/07/03)
$ ruby -v
ruby 1.8.1 (2004-04-05) [i686-linux]

Good. It has been fixed.

The problem was loading, not emitting:
$ ruby -v -ryaml -e 'puts ":not_a_symbol".to_yaml'
ruby 1.8.1 (2004-04-05) [i686-linux]
--- ":not_a_symbol"

$ ruby -v -ryaml -e 'puts YAML::load("--- \":not_a_symbol\"").class'
ruby 1.8.1 (2004-04-05) [i686-linux]
Symbol

Thanks,
Guillaume.
