ah okay.

I quickly compared both variants and realized again, that with the 
panic, we can pretty debug print the structs, making it quite a bit 
easier to compare the expected result to the actual one.

With the output we get from `assert_eq` it can be very cumbersome to 
actually see the diff and why the test failed since the data structures 
can be quite large.

Instead of hacking or own pretty print, we could maybe think about using
