2. Technically, one could port the Julia compiler itself to WasmGC and get full REPL/eval semantics. However, App Store Guideline 2.5.2 states "Apps [...] nor may they download, install, or execute code which introduces or changes features or functionality of the app, including other apps.". It's not clear if this only applies to downloaded code or also local code (e.g. a playground app). If you attempt it, there is a good chance Apple will update their guidelines specifically to ban it. :P
