Would it make sense to add an additional exercise to move_semantics?

[feoh]

Rustlings is amazing. Heartfelt thanks to everyone involved.

I just finished move_semantics6.rs which I found quite tricky but very helpful once I solved it and understood the necessary syntax to implement ownership in one spot and borrowing in another.

Would Rustlings benefit from another similar, perhaps just a smidge more complex exercise given the tricky nature of the subject matter?

Thanks again in any case! Just a thought :)
