Show HN: Scheme with first-class continuations implemented in various languages

I timed each implementation in solving 6-Queens[1] on a meta-circular Scheme[2] (i.e. each Scheme interpreter ran a meta-circular Scheme interpreter to solve 6-Queens). Results are shown in [3]; the order of speed is observed as follows:

Go ≈ Java ≈ Crystal(Compiled) ≈ SBCL > C# ≈ PyPy > TypeScript(Node.js) ≈ Crystal ≈ Dart >> PHP > Python ≈ Ruby
