Rather than wait, I figured I'd experiment with relishapp with my gem Saxerator. It looks like the triple backticks are the way to go: https://www.relishapp.com/soulcutter/saxerator/v/0-7-1/docs/dsl-predicates/all

I will make the necessary modifications to this pull request. Thanks for catching this, it was a learning experience for me playing with relishapp!
