Interval match patterns won't parse namespace specifiers correctly

[simias]

The following code:

use m::{START, STOP};

fn main() {
    let i = 12u32;

    match i {
        20...30           => println!("ok"),
        START...END       => println!("still ok"),
        m::START...m::END => println!("bad"),
        _                 => (),
    }
}

mod m {
  const START: u32 = 4;
  const END:   u32 = 14;
}

Produces this error:

<anon>:10:17: 10:20 error: expected one of `::`, `=>`, or `|`, found `...`
<anon>:10         m::START...m::END => println!("bad"),
                          ^~~

Putting parens around m::START and m::END doesn't fix it.

Also, it doesn't work too (Should?):

struct Struct {
    x : u8
}

const C : Struct = Struct { x : 5u8 };

fn main() {
    match 3u8 {
        C.x ... 2u8 => { println!("bad"); }
        2u8 ... C.x => { println!("bad"); }
        _ => {}
    }
}
