    Nice!

    Interesting that you have used bracket notation for the Do iteration; that is, {x[5 0 4 1 3 2]}[5;i] rather than 5 {x[5 0 4 1 3 2]}i. I dont think it does anything for you here, but it means you could get a unary {x[5 0 4 1 3 2]}[5;] to use in a composition.

    Now

    1. Can you do the shuffle without a lambda?
    2. Try using cut for the envoi
