`move` not needed?

[rvignolo]

I believe that there is no need to use move here:

100-exercises-to-learn-rust/exercises/07_threads/02_static/src/lib.rs

Lines 10 to 11 in d347d1f

	let handle1 = thread::spawn(move || slice1.iter().sum::<i32>());
	let handle2 = thread::spawn(move || slice2.iter().sum::<i32>());

What do you think?

Thank you for the tutorial!
