// Regression test for #15896. It used to ICE rustc.

fn main() {
    enum R { REB(()) }
    struct Tau { t: usize }
    enum E { B(R, Tau) }

    let e = E::B(R::REB(()), Tau { t: 3 });

Switch to purely namespaced enums This breaks code that referred to variant names in the same namespace as their enum. Reexport the variants in the old location or alter code to refer to the new locations: ``` pub enum Foo { A, B } fn main() { let a = A; } ``` => ``` pub use self::Foo::{A, B}; pub enum Foo { A, B } fn main() { let a = A; } ``` or ``` pub enum Foo { A, B } fn main() { let a = Foo::A; } ``` [breaking-change] 2014-11-06 08:05:53 +00:00			`let e = E::B(R::REB(()), Tau { t: 3 });`
