I'm a big fan of RecordStream. Everyone should definitely give it a look.

However, is it true to say that recs has this functionality? RecordStream is great with sequences of relatively simple JSON structures, where you want to count, group, collate, etc. the sequence. It looks like jq is better able to handle large, complex arbitrary JSON objects, pulling out deeply nested fields and transforming them. For example, how would you implement jq's "recurse" in RecordStream?

Now what would be really cool is using the two tools together :-)
