    Lean is currently moving to the 4th iteration which is the first intended to be a general-purpose programming language. It "is currently being released as milestone releases towards a first stable release". For now the main goal is to port mathlib to the new version, and then they will concentrate on the compiler. So it is not production ready. But that doesn't mean it is not suitable for building any programs now. There is a simple raytracer written in Lean [1]. I have built a chip8 interpreter with it and the only problem was the lack of an ecosystem, meaning I had to build the necessary libraries myself.

    Now it has a RC GC and boxes everything >= 64 bits, and as the compiler isn't polished it is probably significantly slower. In the referenced raytracer repo you can find rendering time compared to the C implementation (Lean is 25x slower, but that was a year ago).
