Method calls don't autoderef

[brson]

Field access does.

impl i for int {
    fn val() -> str { "wut" }
}

fn main() {
    let j = @{
        val: 10
    };
    // This autoderefs
    assert j.val == 10;

    let i = @10;
    // This does not
    assert i.val() == "wut";
}

../src/test/run-pass/method-autoderef.rs:12:11: 12:16 error: attempted access of field val on type @int, but no public field or method with that name was found
../src/test/run-pass/method-autoderef.rs:12     assert i.val() == "wut";

I've been thinking about this for a while, actually. The reason is clear: it's nice to make impls over types like @T, and if we always auto-deref'd prior to scanning for impl matches, that wouldn't work. I don't know if the right behavior is to scan for matches with the original type, then auto-deref, then scan again, or what. It's an annoying problem.

Niko fixed this, right?
