Hoot: Scheme on WebAssembly

Hoot is a Spritely project for running Scheme code on Wasm GC-capable web browsers, featuring a Scheme to Wasm compiler and a full-featured Wasm toolchain.

Hoot is built on Guile and has no additional dependencies. The toolchain is self-contained and even features a Wasm interpreter for testing Hoot binaries without leaving the Guile REPL.
