error[E0308]: mismatched types

LL | let _: fn(&mut &isize, &mut &isize) = a;
| ^ one type is more general than the other

= note: expected fn pointer `for<'a, 'b, 'c, 'd> fn(&'a mut &'b isize, &'c mut &'d isize)`
found fn item `for<'a, 'b> fn(&'a mut &isize, &'b mut &isize) {a::<'_, '_>}`
= note: when the arguments and return types match, functions can be coerced to function pointers
error: aborting due to previous error
