Hi, I have totally confused myself with arrays. I have an anon 2d array (arbitrary size) that looks like this:
$a = [[1,2,3],[4,5,6]...]
and I want it to transform it to look like this:
$b = [[1,2],[3],[4,5],[6]...]

Ok in formulating my question I think I solved it: 
foreach $row (0..$#A){ #array row length
  foreach $col (0 .. ($#{$A[0]} - 1) ) { #array width less one
    $b->[$row*2][$col] = $a->[$row][$col]; # copy all but last ele ove
+r
  }
  $b->[($row *2) +1][0] = $a->[$row][$#{$A[0]}]; #now copy last
  #there are twice as many rows so we double the row index
}

Solved - but is there a neater way? Array slices? z
