Cannot declare unsafe impl functions

[erickt]

I would expect that interfaces and implementations would support declaring a function as unsafe but it doesn't seem to work:

impl foo for [u8] {
    unsafe fn from_bytes() -> str { str::unsafe::from_bytes(self) }
}

fn main() {}

Errors out with this:

test.rs:2:4: 2:10 error: expecting fn, found unsafe
test.rs:2     unsafe fn from_bytes() -> str {
               ^~~~~~

Similar behavior for a pure fn:

joshua@escape:~/rust/rlambda$ rustc lambda.rc
./lambda.rs:36:2: 36:6 error: expecting fn, found pure
./lambda.rs:36
                 ^~~~
