error[E0369]: binary operation `==` cannot be applied to type `for<'a> fn(&'a i32) -> &'a i32 {foo}`

error[E0277]: `for<'a> fn(&'a i32) -> &'a i32 {foo}` doesn't implement `Debug`

= help: the trait `Debug` is not implemented for fn item `for<'a> fn(&'a i32) -> &'a i32 {foo}`
= help: use parentheses to call this function: `foo(/* &i32 */)`
