Can't use symbolic enum in struct constant

[burg]

Not exactly sure what's going on here. The string and enum seem to be two separate errors.

Test case

enum Weight {
    Light,
    Medium,
    Heavy,
}

struct Bike {
    name: ~str,
    weight: Weight,
}

const town_bike: Bike = Bike {
    name: ~"Schwinn",
    weight: Heavy,
};

pub fn main() {
    debug!("%?", town_bike);    
}

Result

[burg@host-5-178 Desktop]# rustc test.rs
test.rs:13:10: 13:20 error: constant contains unimplemented expression type

Yeah, you can't use enums in constants at all. If we want to revisit that, it would have to be an RFC. (It would certainly make sense to use C-like enums, anyway.)

At the least, maybe we should document the "conditions for success" somewhere 😉
