The trick is to use a [#slice] to extract the information to sort
about ; however the [#slice] needs to know the height of the grid, so
you need a [#dim]. the [#unpack] and msgbox is only one way to do it in
two steps : you can also do [# * (1 0)] [# + (0 1)] and there are a
bunch of other equivalent ways. Then, when you have a grid of size (n 1)
and you need to get it to size (n), you'd do something like [#fold +] or
[#fold put],
Actually, in the case where you only want the last column, you can skip
[#slice] and [#dim] and just use [#fold put].
Therefore, if you only want the last column, you can flip the grid using
[#reverse 1] before using [#fold put].
And if you know the number of columns in advance, you can select the
column using a one among zeroes, as in [#inner (5 # 1 0 0 0 0)], which in
this case is the same as [# * (1 0 0 0 0)] then [#fold +] (this
equivalence only works with simple cases of #inner, those where the
right-inlet has only one dim)
