Matz gets together with Anthropic's Claude to create an experimental ahead-of-time compiler for Ruby – though with many limitations

Yukihiro Matsumoto - better known as Matz - is building Spinel, a native compiler for Ruby, with help from Anthropic's Claude Code.

 under the MIT license, works by parsing Ruby code into AST (abstract syntax tree) files, then converting it to C code for compilation by a standard C compiler. In Matz’s tests, Spinel-compiled code runs approximately 11.6 times faster than MiniRuby - a stripped-down Ruby build - using the in-development Roby 4.1.0. 

The output is C code, compilable to a native executable via gcc (GNU Compiler Collection) on Linux or Windows (with MinGW - Minimalist GNU for Windows), or via LLVM's Clang on Linux or macOS. BSD will "probably work", according to the readme, but is not tested.
