Function `where` clauses with trait arguments fail

[michaeljklein]

Aim

Attempted to use a trait in a function with a where clause:

trait Foo<A> {
    fn foo(self, x: A) -> bool;
}

// This works:
// fn bar<T, U>(x: T, y: U) -> bool where T: Foo<U> {
//     x.foo(y)
// }

// This fails:
fn bar<T, U, V>(x: (T, U), y: V) -> bool where (T, U): Foo<V> {
    x.foo(y)
}

Expected Behavior

Expected both functions to type check

Bug

The trait fails to resolve:

error: No method named 'foo' found for type '(T, U)'
