So you've got the "cannot borrow immutable local variable `vec1` as mutable" error on line 13,

Yes, it would be really easy to fix this by just changing the value bound to `word` to be a
string slice instead of a `String`, wouldn't it?? There is a way to add one character to line
12, though, that will coerce the `String` into a string slice.
