CS-FSSA-029
The following snippet emits a wrong/confusing error message, because a for loop only gets
type-checked in its desugared form, as a while loop:

fn main() {
 let mut v : Vec<u8> = Vec::new();
 v.push(1);
 v.push(2);
 v.push(3);
 for elem in v.iter() {
 log(elem);
 3
 };
}

The error message is the following:

A while loop's loop body cannot implicitly return a value.
Try assigning it to a mutable variable declared outside of the loop instead.
