I recently discovered the issue for myself, that you can write the following code:

for i in 10..1{
println!("Hello World");
}

This code does nothing, but you dont get a compiler warning and nothing and this isnt described in the rust handbook either. I dont think I can be the only beginner stumbling over this, so theres a possible solution. I dont know if the way I wrote it fits in with the writing style of the book, but just adjust it as needed :)
