A metatable can be defined like

local t = setmetatable({}, {
  __tostring = function() return 'custom tostring behavior!' end
})

Instructions

You will need a copy of this helix fork (works for sure in this commit, in case breaking changes happen)

Follow instructions in STEEL.md (you might need to add +stable after cargo to all commands if you get helix-term build errors, f. e. cargo xtask steel will become cargo +stable xtask steel) to install helix and steel and don't forget to run cargo xtask code-gen (or cargo +stable xtask code-gen) after you install helix to generate bindings

Copy all files in this gist into your helix config directory (game-of-life.scm into cogs subdirectory inside)
