Me neither ;)

to me, I always change next/prev pointsers manually, so I have the
feeling of what I have to do.
But shouldn't the node.insert_* just do the same?
They do, as far as I can tell.
Well … Taco? What does the master say? Are they equal?
Alternate solution which reverse all nodes in a list:
Well, I don't want to reverse all nodes. That may be ok for the
all-glyphs-in-a-line, but not for all-lines-in-a-paragraph, as there may
be (or, is) other vertical material that should stay where it is.
Still, thanks for your code, it's also a good starting point for me.

function invert_list (h)
local l
for n in node.traverse(h) do
if l then
l = node.insert_before(l, l, node.copy(n))
else
l = node.copy(n)
end
end
node.flush_list(h)
return l
end
Best,
