Given a variable vec of type Vec<Item> where Item is not Copy,

Simply writing vec[index] would cause error:

return vec[index]; // error: cannot move out of `vec`

So I must wrote this convoluted code:

vec.truncate(index);
return vec.pop().unwrap();

This looks inefficient and stupid.

Is there a better way? (I don't need the rest of vec after I have vec[index])
