Fair enough, I think. 

The biggest problem with YAML is that MRI 1.8.7 is pretty bad at dumping Unicode characters into YAML and most of this gem is about Unicode. @camertron tried to solve it by adopting parts of `ya2yaml` gem internally in TwitterCLDR and probably that's also the reason why `ruby-cldr` uses `ya2yaml`. It fixes some issues, but the differences between all these YAML implementations are causing a lot of troubles :(
