Matching on a function causes "found structure or enum pattern"

[huonw]

mod foo { pub fn bar() {} }
fn main() {
    match () {
        foo::bar => {}
    }
}

function-match.rs:4:9: 4:17 error: mismatched types: expected `()` but found an enum or structure pattern
function-match.rs:4         foo::bar => {}
                            ^~~~~~~~

This should be complaining about mismatched types.

(The module is necessary to force the compiler search/use the function; with just bar => {} it takes bar to be a variable binding.)

I agree, it should probably mention the exact type it found.
