// Test that we are able to compile the case where both a blanket impl
|

// and the object type itself supply the required trait obligation.
|
|
// In this case, the blanket impl for `Foo` applies to any type,
|
|
// including `Bar`, but the object type `Bar` also implicitly supplies
|
|
// this context.
