It’s certainly possible.

An type system can’t be both sound and cover all cases. Rust had made certain trade offs, and some weird edge cases regarding generic lifetimes still cause UB.

If you compile to rust you’ll be forced to inherit all the decisions Rust had made over the years, and won’t be able to tune then to your use case. That may it may not be a problem for you.

Code golf:

If you think there is no way eval can save bytes, there is

A backdoor requires malicious intent, otherwise it’s just a vulnerability

The exploit requires physical access. It’s not exploitable in 99% of cases

But is it fast?
