Because each closure generates its own environment `struct` and implementation

The error also points out that the return type is expected to be a reference,
453-
but what we are trying to return is not. Further, we cannot directly assign a
454-
`'static` lifetime to an object. So we'll take a different approach and return
455-
a "trait object" by `Box`ing up the `Fn`. This _almost_ works:

But why doesn’t our closure implement `&'static Fn`? Well, as we discussed before,

closures borrow their environment. And in this case, our environment is based

on a stack-allocated `5`, the `num` variable binding. So the borrow has a lifetime
454+

over, the stack frame would go away, and our closure is capturing an environment
