Why would it be UB? All objects are behind (thin) pointers, which can be overwritten atomically.

I don't understand – what's the point of not collecting mass amounts of personal identity documents and face scans and linking them to online identities?

I do the same in my toy JVM (to implement the reentrant mutex+condition variable that every Java object has), except I've got a rare deadlock somewhere because, as it turns out, writing complicated low level concurrency primitives is kinda hard :p

They're great, compared to cars. But while they have a relatively fast and cheap setup, over the long term light rail and trams are a lot cheaper to run and can coexist with foot & bike traffic easier since the rails make them very predictable.

I thought it was because you couldn't be fully generic over exceptions.

merde_json should also be relatively small.

Me likewise – it makes me happy that there's an 800 word article about a pond that used to exist for less than 200 years in my town.

That would be great if it was possible, but how do you specify & implement sensible behavior for this:

    void foo(int *a, int b) { a[b] = 1}

At runtime there is no information about whether that write is in bounds and no way to prevent this from corrupting arbitrary data unless you compile for something like CHERI.

Afaik for the WebAssembly MVP, the goal was to have a simple, efficient compile target - therefore only integers and floats. To make wasm more useful & easier to integrate, the plan calls for interface types[0], which allow both accessing complex (JS) objects and calling browser APIs.
