Putting a lifetime on @ skips the next token and forces fn.

[huonw]

fn main() {
    // expected `fn`, but found `;`
    // let _: @'static int;

    let _: @'static whatever fn();
    let _: @'static + fn() = || {};
    let _: @'static for fn() = || {};
    let _: @'static "a string" fn() = || {};
    let _: @'static 'a fn() = || {};

    // Illegal lifetime: named region `&'a` not in scope here
    // let _: @'a whatever fn();
}

The last example is just showing that the 'static actually get parsed as a lifetime.

My PR only fixes the skipped token. I assume forcing fn is actually correct, because what other @-boxes have lifetimes?
