Incorrect Compiler Error

[Kleptine]

When running the following (clearly broken) program, the compiler spits out a completely incorrect error message:

fn main() { 
    println!(format!("foo"))
}

Results:

<anon>:2:14: 2:20 error: macro undefined: 'format'
<anon>:2     println!(format!("foo"))
                      ^~~~~~
<anon>:2:14: 2:28 error: format argument must be a string literal.
<anon>:2     println!(format!("foo"))
                      ^~~~~~~~~~~~~~
error: aborting due to 2 previous errors
playpen: application terminated with error code 101

While the second is correct, the first is wrong, confusing and suggests that format! needs to be imported somehow.
