> 2. We will be targeting WasmGC in the near future, so we need our core runtime and compiler data structures to be compilable without the assumption of necessarily having linear memory available.

Big if true. Does that mean we'll get a no-alloc iOS backend?

I'm not sure I understand the connection, but I also know basically nothing about iOS.

1. iOS doesn't allow JIT for apps distributed through the App Store. However, WASM (including JIT) is allowed. Effectively, this would allow Julia to run on i(Pad)OS.

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

1. Don't forget that there are parallel efforts for static compilation in Julia - a static artifact should be able to get through the App Store.
