How to get this working? (I hope I don't annoy you by asking
that much questions, but I've got the feeling, that I've got
only two choices: To shy away from using immutable (like I did
in the last three years) or ask a lot of questions in the hope
of understanding what's going on...

Difference is, retro lazily iterates in reverse order, while
reverse eagerly reverses in-place.
Don't worry about asking questions - it's a good way to learn,
and we like helping. :) Immutable is not very well supported
everywhere in the library, sadly. It seems an important building
block would be something like Reassignable!T, which would hold a
struct with immutable members, and still be reassignable with
different values.
