14 fn foo<F:Default=usize>() -> F { F::default() }
15 //~^ NOTE: a default was defined here...
17 fn bar<B:Debug=isize>(b: B) { println!("{:?}", b); }

21 // Here, F is instantiated with $0=uint
23 //~^ ERROR: mismatched types
24 //~| NOTE: conflicting type parameter defaults `usize` and `isize`
25 //~| NOTE: ...that was applied to an unconstrained type variable here
27 // Here, B is instantiated with $1=uint, and constraint $0 <: $1 is added.
29 //~^ NOTE: ...that also applies to the same type variable here
