It's certainly possible, but if you want the output YAML to look like that
you're going to need to put the *input* data into the same sort of format.
For instance, running the expected output (with quotes around 01, to avoid
it being parsed as an integer) through YAML.load gives this Ruby result:
{"en"=>{"01"=>"red, green"}}
