@PaniczGodek a first time project started in Scheme, before discovering that Common Lisp is better 🙂
@PaniczGodek maybe Scheme88 that is an implementation of Scheme in CL, or "BBN Butterfly Common Lisp" that is an implementation of CL in Scheme.
@mzan the repository contains two implementations of the same thing: one in Scheme and one in a CL, too
@mzan a hint: it is a project conceived by a very experienced Lisper
