Ask HN: Is there a decent configuration format?

Hey all,

I'm working on bot protection software and something I've run into is that YAML landlines can and will hit you at the worst times possible. Is there a configuration format that makes it easy to use for less technically apt people and lets you write regular expressions without having to double escape backslashes in strings? I also need it to have good support in Go, ideally with a way to get the same semantics as encoding/json.

Thanks in advance!
