A Scheme engine that aims¹ for R⁵RS compliance. Also, a study or an étude for my daily hacking exercise.

You'll find almost nothing unique or interesting here; this is just one of those plain and old-fashioned interpreters in C (C23 with some extensions).

Our milestones will be available at the project page.

• Selectable GC Algorithms
  • You can choose the GC algorithm using the --gc=<epsilon|mark-sweep|...> option at startup.

• Both "Scheme" and "Schaf" begin with Sch. So we can use the prefix sch_ for our exported symbols in both senses.
• It's like me who got lost.

• libscary: A (scary) scalable array library in C.
  • Dynamic-extended, type-safe-on-push, and zero-overhead on read/write
