[wip] Change of approach: moving the Multistatus 

Move the Multistatus value from the main function into the traverse
function, as it will not be used in the main function afterwards.
In the traverse function, the struct is now borrowed as mutable,
which fixes the append function, but we'll probably need to use
references in all the match arms.
