I'm writing R5RS Scheme _interpreter_ implementation in Kotlin (previously in Java): https://github.com/kovrik/scheme-in-kotlin/

It is a hybrid of R5RS Scheme + some things from Kawa, Racket and Clojure. It doesn't have a proper name and documentation yet.

I'm writing it as a hobby sandbox project, for learning purposes and fun. Trying to keep it simple and easy to understand (some things are not perfect though).

Features:

- full numerical tower

- lists, vectors, maps, sets, arrays

- symbols, keywords, strings (mutable/immutable), patterns (regexes), chars

- one-shot upward continuations

- Java interop

- futures, promises, delays, boxes (atoms)

Not implemented yet:

- macros

- persistent data structures

- compiler

- bugfixes :)

PS: it is a pleasure to write it in Kotlin. Great language!
