the pattern 'x()' should not be a legal identifier pattern

[jbclements]

It should not be possible to use x() as a match pattern, like this:

fn main() {
    let z = match 3 {
        x() => x
    };
    assert_eq!(z,3);
}

I have a fix for this, I'm just adding it to get an issue number.

fixed, now. closing.
