show off how tricky they can be. Something without pointers. Something
that is impossible to crash.

No nontrivial language can ever be proven to be imposible to crash.

I'd be satisfied with no known crash instance in the history of the
language. Provability was a CS fad, until they discovered that they
couldn't prove anything useful.
