JOPA: Java compiler in C++, Jikes modernized to Java 6 with Claude

Essentially, I've tried to throw a task which, I thought, Claude won't handle. It did with minimal supervision. Some things had to be done in "adversarial" mode where Claude coded and Codex criticized/reviewed, but it is what it is. An LLM was able to implement generics and many other language features with very little supervision in less than a day o_O.

I've been thrilled to see it using GDB with inhuman speed and efficiency.

I am very impressed with the kind of things people pull out of Claude's жопа but can't see such opportunities in my own work. Is success mostly the result of it being able to test its output reliably, and of how easy it is to set up the environment for this testing?

Jopa means ass in russian, this reminded me of Pidora.
