btw any plans to use the yaml-rust's function Yaml::from_str? so that one would not have to implement these things twice? see chyh1990/yaml-rust#114

I don't see 0b in the yaml 1.2 spec http://yaml.org/spec/1.2/spec.html. Where is this behavior specified?

[p4l1ly]

ok, now I can see it is not in the core schema, but in the YAML tag repository, which is referenced in the section 10.4.

The 0b format is however supported in some other yaml parsers, e.g. pyyaml. Maybe it could be a tiny reason for merging this?

Ah, I didn't look at the tag repository. I suppose that's good enough. Thanks!
