Sort of, I use it in my own scripts because it's cleaner to code in than JavaScript and I still enjoy the syntax. But I'll admit that I no longer have the time to update it to the latest standards (ES5 support should probably be dropped altogether in favor of using Babel to do the work). If someone else wants to take the project over, I'm more than happy to give you admin access. There is another project I started on the side for type/state tracking (like TypeScript) called Interstate, and I have more recent code on my secondary laptop than the one in the repo (
https://github.com/atsepkov/Interstate) which uses promises to go back and resolve types it may not be aware of at the time of original parsing. I wanted to eventually merge Interstate into the same project but last year I've taken more than I can chew with regular work and haven't had the time to do so.
