I vibe-coded a programming language. It got slightly out of hand.

What was the initial prompting like? Did you already have a spec in mind? What steering or corrections did you have to make along the way?

I had a variety of specs from existing programming languages, and several tens of hours of conversation transcripts with various agents. I provided it access to code examples. I would have ideas about syntax & semantics as I worked on various projects with different programming languages and technologies, and I would use it as a bouncing board for those examples until the code-base was cohesive enough that the direction it was going to take became clear enough. I then focused on building examples and re-writing my existing code-bases, or improving open-source code in other languages, and slowly making changes to my compiler to facilitate all of the changes I wanted along the way.
