GC and Exceptions in Wasmtime

It seems like a bit of a shame that wasm got support for exceptions but doesn't support effects which are a generalisation of the same concept. https://wasmfx.dev/

I'm guessing this may be because exceptions exclusively require stack unwinding where as effects require full stack switching.

Seems like there is still progress on that though which gives hope https://github.com/WebAssembly/stack-switching/blob/main/pro...

WASM will be ready when GNU Hurd succeeds in running the desktop linux of the year. Already 10 years since WASM ... HTML, CSS and JavaScript all had a huge influence. WAS simply has not done so yet.

Does it support interior pointers?
