error: lifetime may not live long enough
--> $DIR/copy_modulo_regions.rs:12:5

LL | fn foo<'a>() -> [Foo<'a>; 100] {
| -- lifetime `'a` defined here
LL | [mk_foo::<'a>(); 100]
| ^^^^^^^^^^^^^^^^^^^^^ returning this value requires that `'a` must outlive `'static`
|
= note: requirement occurs because of the type `Foo<'_>`, which makes the generic argument `'_` invariant
= note: the struct `Foo<'a>` is invariant over the parameter `'a`
= help: see <https://doc.rust-lang.org/nomicon/subtyping.html> for more information about variance
