Glad that the soundness bug was caught so quickly, and that the new version has been put out so quickly. Thanks Rust team!

A Rustacean with a wry sense of humor suggested that now would be a good time to pitch the Underhanded Rust Contest https://underhanded.rs/blog/2016/12/15/underhanded-rust.en-U...

I'm new to rust. Can someone explain what is the issue with following code?

    pub fn as_mut_slice(&self) -> &mut [T] {
        unsafe {
            slice::from_raw_parts_mut(self.ptr as *mut T, self.len())
        }
    }

The post goes on to explain it, was there something specific about that that's confusing?

My confusion was why the compiler didn't catch this, it is suppose to spot this sort of thing right?

Now that I think about it, maybe it has to do with `unsafe` block so the compiler doesn't check it.

My next question would be why does it need `unsafe`?
