What it was for

Why it's here
Announcement at a conference is one moment; delivery is when the language became usable in the wild.
Why it mattered

What it solved
TeamsMicrosoft Teams — chat, video calls, and Office integration for workplace collaboration. needed a working compiler on real hardware, not just a paper specification.
