Not sure what you meant by this example since it doesn't compile. It seems the borrow checker caught your mischief. So much for effectively disabling stuff :P
You haven't effectively disabled anything; you just (tried to) wrote unsound code that washes one mutable ref as another. This stuff is allowed provided shared refs are never accessed at the same time (for example, panicking upon reading reference_b).
What you probably meant is https://play.rust-lang.org/?version=stable&mode=debug&editio...
But you know what? If you're dabbling in unsafe, you have this big button called Tools in the playground. Choose Miri, then run your code; it will display large Undefined behavior. It even highlights the `trust_me_bro` function.
Hell, run this with UBSAN, ASAN, and other C tools. They will probably catch any such behavior.

You're just splitting hairs and trying to weasel around the fact that yes, you really can create any lifetime you want using unsafe.

That's because the crappy HN formatting ate some of the characters. Here's the original version:

If you know what I meant, then what's up with your snarky comment about "So much for effectively disabling stuff"? In your playground link, you did effectively disable the borrow checker in safe parts of the code. Next thing you're moving the goalpost, now it's not about external, static analysis tools: "run this with UBSAN, ASAN, and other C tools". I don't think you're arguing in good faith here. Goodbye.
