It said in the article that you can't.
The compiler defines a new ABI and you can't link system ABI libs with it.

Mixing safe and unsafe

But that's not what I meant. I know the ABI is different. But within one compiled program, all using the new ABI, can you declare a block as "unsafe" so that the compiler won't emit instructions for bounds checking (for example) within that block?
