    Great, thanks, did not see this idea.

    Best regards

    #2((2 1) ((+ 2 3) 6))

    Hmm... I see they implemented quasiquotation for vectors but not
    for arrays:

    scheme@(guile-user)> `#(1 2 ,(+ 3 4))
    $1 = #(1 2 7)
    scheme@(guile-user)> `#2((1 2) (,(+ 3 4) 5))
    $2 = #2((1 2) ((unquote (+ 3 4)) 5))
    scheme@(guile-user)>

    I suggest you file a feature request for that.
