I've spent 2 weeks (2-4h per day) to make D language[1] version of Sciter SDK [2]
Choice of AI "tooling" was by accident - typed something like "how to define copy constructor in D for custom structure" in Microsoft's Copilot in Edge browser that gives context for AI.
The answer was good enough for me and so I went with it further.
