Really excited to see where this goes. Some time ago, @jart answered a message about using pledge() as WASM alternative [0], which made me believe this could be an alternative to using WASM when you just need a sandbox. I would love to be able to run arbitrary code without having to deal with containers, microVMs or having to use a language that supports WASM [2]

[2]: Even for the languages that support WASM, you usually have to deal with incompatible dependencies, properly configuring your compiler, etc.
