error[E0277]: can't compare `Foo` with `Foo`
--> $DIR/issue-87429-associated-type-default.rs:13:60

LL | type Member<'a>: for<'b> PartialEq<Self::Member<'b>> = Foo;

= help: the trait `PartialEq` is not implemented for `Foo`
note: required by a bound in `Family2::Member`

LL | type Member<'a>: for<'b> PartialEq<Self::Member<'b>> = Foo;
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ required by this bound in `Family2::Member`
help: consider annotating `Foo` with `#[derive(PartialEq)]`
