Eg, picking out a diagonal with a shared array:

    (equal? (make-shared-array #2((a b c) (d e f) (g h i))
                               (lambda (i) (list i i))
                               '(0 2))
            #(a e i))
    => #f

but with array-equal? it's #t.

It was this way in guile 1.6 too, but never really documented under
equal?, unless you know or thought a shared array is not really an
array.
