what you propose is much more sensible -in fact it should have been done this
way with an item flag to begin with.

ok. i see your problem.
let's say you have the following:
a
b
c
HEAD1
x
y
z
HEAD2
i
j
k
HEAD3
f
g
h
HEAD4
l
m
n
HEAD5
o
p
q
HEAD5
r
s
t
u
v
w
as such i actually can't see a way to build that with anything other than
append and prepend. insert before/after wont do what you want. if i had to add
HEAD4+ l,m,n in that wasn't there to start with, i couldn't actually do it
without rebuilding. it would require that insert before/after gets a parent
param. i see no way around that. and so... that means the api has to break.
