Scott,I have detected unnecessary dependencies around copilot. Among others, the dependency on ansi-terminal may be removed.
I am opening issues for them: https://github.com/Copilot-Language/copilot/issues?q=is%3Aissue+depend+unnecessary.
I have sent a PR for the issue with bimap and I'm waiting for that to be merged: https://github.com/joelwilliamson/bimap/pull/16
All the best, Ivan
