Create a library with the following `src/lib.rs`: ``` rust pub trait SomeTrait { type Typ; } pub struct Foo<T> { bar: T } impl<T: SomeTrait> Foo<T> { pub fn foo(&self, bar: T::Typ) {} } ``` and run `cargo doc`. The documentation will show the type of `Foo::foo` as `fn foo(&self, bar: T)` and not `fn foo(&self, bar: T::Typ)` as expected. `rustdoc 1.0.0-beta (9854143cb 2015-04-02) (built 2015-04-02)`
