Nim
Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. Its design focuses on efficiency, expressiveness, and elegance (in that order of priority).
Project mention: F*: A general-purpose proof-oriented programming language | news.ycombinator.com | 2026-08-02There's nim [1] which is aiming for the same thing - syntax similar to python and performance similar to C++, zig etc.

codetracer
CodeTracer is a user-friendly time-traveling debugger designed to support a wide range of programming languages.
Improving code understanding is the main focus of my work and thinking right now. If we want to make advances I believe that we should rely more heavily on one key quality of the program code: It is meant to be executed.
Here are some ideas:
1. Time travel debugging. Reading a PR just like a wall of text is difficult, but what if you could step through the PR and see the state at a given line for some test executions? Time travel debugging can make this possible. You would collect a debug trace and use it to overlay the PR diff with additional controls and information to resemble a debugger's UI. I was part of the team behind Codetracer (https://github.com/metacraft-labs/codetracer) who is trying to work in this direction.
2. Test suites and coverage. We don't use them enough for understanding right now. The test suite encodes what features the code is supposed to have, and the coverage tells us where in the code those features are implemented. I'm playing with an idea about this here: http://atlas.vihren.dev When we intersect coverages for the different test cases we can arrive at code segments which represent "atomic behaviors" present in the code. They form a mathematical structure which can be represented as a graph. I am currently exploring what value we can extract from it for the benefit of both humans and agents.

Project mention: Show HN: Nimic – Pure Python as a systems language with AOT compilation | news.ycombinator.com | 2026-06-23
Currently, Nim fits quite well with Python but there is a project to directly emit LLVM IR from Nim and MIR might be relevant there: https://github.com/arnetheduck/nlvm

NimForUE
Nim plugin for UE5 with native performance, hot reloading and full interop that sits between C++ and Blueprints. This allows you to do common UE workflows like for example to extend any UE class in Nim and extending it again in Blueprint if you wish so without restarting the editor. The final aim is to be able to do in Nim what you can do in C++
