"expecting a type here because of type ascription" when forgetting a :

[progval]

In the following code, I forgot a semicolon:

fn main() {
    Box:new("foo".to_string())
}

This generates the following error:

  |
2 |     Box:new("foo".to_string())
  |             ^^^^^ expecting a type here because of type ascription

This may get confusing when nesting multiple calls in the argument of Box::new.
