1 error: lifetime may not live long enough

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