A five-star bake. Worth schmearing, sharing, saving.
Summary
Spinel is a Ruby AOT (Ahead-of-Time) compiler that compiles Ruby source code into standalone native executables. It uses whole-program type inference to generate optimized C code, achieving approximately 11.6x speed improvements over CRuby (miniruby). The compiler is self-hosting, meaning its backend is written in Ruby and compiles itself into a native binary. The project is hosted on GitHub under the matz/spinel repository, with 74 passing tests and 55 passing benchmarks.
