Literals don't live long enough

fn main() {
    let x = "".as_slice();

Similarly you can't pass an array literal to BufReader.

let x: &'static [u8] = [0] doesn't work either.

This now compiles without error.

The first one compiles, but the second one is trying to assign a static lifetime to a slice on the stack, which is invalid.

The correct workaround for the second one is to use const y: &'static [u8] = &[0];
