This looks great, thank you!

I'll wait to merge and publish until we know which release PR 66 will be a part of.

BTW I recently granted you write permissions to sywac repositories (I didn't realize members only had read access by default), so feel free to clone the original repos (instead of using forks) and push your branches to the origin remote - that will allow us to pull from and push to the same branches, if necessary.

Also, I can't tell you how much I appreciate your involvement with sywac. You're really helping to progress this library forward, and it's awesome. Thank you!

👍 Thanks for building it. :)

(I'll let any current open PRs progress naturally, but I'll make sure to open new ones from the origin.)
