Also I want to also put out the request for wasm64 support if it's not already on the roadmap. Just spent a few hours working on (the start of) golang support with @Huijiro and apparently golang doesn't support wasm32 currently (it's in development, but it seems like they're stalling on it due to other higher priorities.) Even if it's still limited to 4GB in the end, I just think it would be nice to not have to do weird pointer casts to int32 just to pass the data back to spacetimedb. I might try and implement it at some point myself, but I don't want to make any promises yet, I already have a lot on my plate.
