Excellent! Thanks!
Welcome! The json-parse function is very fast - crunches about 50Mbyte of data per second on a MacMini 2.3Ghz Intel Core i5 - Suitable for big data.
Very nice. Any plans for doing the same for yaml?
Here are the Google counts for the three:
~> gc XML JSON YAML
XML -> 928,000,000
JSON -> 67,000,000
YAML -> 4,030,000
~>
I imagine JSON getting closer in popularity to XML over the next years, but don't think this will happen to YAML. At least at the moment there are no plans for a yaml-parse.

Hmm... Fair enough.
I see them as serving different purposes though. JSON is fine for machine-machine interfacing, but not well suited to human editing. YAML is much friendlier in that department.
