I'm doing this right now with Codex. It's currently working on porting the Binder.

7-11 phases to go and so far it looks like it might only cost $100. I'm focusing on efficient execution strategy minimizing token in/out, turns, and rework.

Will prob post up something interesting when it's done.

I don't have 400k to burn(lol) but with union types now in C# 15...

I wonder how few tokens it could be done in. Might be relatively easy work compared to Rust.

Give it the goal of native AOT.. Have it profile and optimize after it gets a working version...

Already did.
