Interesting video. There is something that I'm kind of confused 
about. The narrator in the video claims that in D popFront 
doesn't consume the element. Is this true? When I do a popFront, 
doesn't it consume the first element in an array for example. Can 
someone clarify this?

Also in Rust, next does consume the element. However, in Rust you 
can iterate over references (which also automatically borrows). 
So iterating over borrowed references does not consume the 
underlying data structure.
