I don't know if this is actually an issue, but test it and ensure it's not:

If somebody overflows the stack with a recursive call, make sure it's recoverable by the ludus-web environment
In particular, make sure it's caught inside Ludus itself.

#29 helps but does not fix this. If recursive calls are in tail position, we won't get stack overflows. But beginners may overflow the stack by non-tail recursive calls, and we don't want that to crash ludus-web.

At current, a stack overflow will cause a wasm out of memory issue; not sure how to recover that.

Meanwhile, an infinite loop will also hang.

Neither of these are recoverable, but hitting reload now automagically puts your code back in the browser, so you won't lose work.

Bumping to next milestone.

This will be possible with the new actor model.
