Strangely enough, this project needed both YAML parsing and JSON parsing (don't ask!). I was able to cannibalize the YAML::Tiny, but I didn't find a similar module for JSON. I started writing a traditional recursive descent parser, and then I remembered that modern regex can do it all internally, so I took a whack at it. You see the result.
