No worries regarding the naming, it's what makes open-source friendly! You can see some benches here e.g. https://travis-ci.org/yamafaktory/jql/jobs/618374730#fold-st... but those actually more like regression tests that are triggered for pull requests to compare them against master (and I should use Github actions probably here now instead of Travis). Thanks for your reply!
Sorry for the name duplication! I thought I'm sharing the name only with the jira API jql.
EDIT: I'd love to see some benchmarks. I expect your jql to greatly outperform mine and jq, considering it's written in Rust!
