And I wonder about MPS & Webr...
I've been looking at https://www.jetbrains.com/mps/docs/MPS_YouTrack_case_study.pdf
where it says "At some point the set of languages we used to develop YouTrack will be released to the public, because we believe there are many teams and
projects out there who may greatly benefit from our innovatove approach to web application development."
What is the current status and what would be the license, if released?
