Currently \writebetweenlist doesn't work as advised. It inserts the

The rule is correctly inserted at http://live.contextgarden.net/ and in
the ConTeXt shipped with TeXlive 2010 (2010.05.24), but not with the
current beta and the 2010.07.30 version. mkii works fine.
It prints
--rule--
List entry A
List entry B
Unfortunately, I can confirm this with current version:

Help please!
There is a good reason for this. Inbetween has multiple usage and
these are conflicting:
- in order to get the right page info associated it needs to be
anchored in the text stream
- in that case a node can interfere with spacing and can come unexpected
- sometimes direct flushing is needed, sometimes delayed
btw, all these issues have been observed by users every now and then
Now, if unexpected interference is the hardest to track down,
inbetween is an immediate action. In principle one can influence that
but it's not that intuitive. So, I've now added an option to (1) the
flushers and (2) the list placers.
The following example shows this:
\definelist[testlist][criterium=all]
\starttext
Regular list entries are bound to a specific location in order to
get the right pagenumber etc.\ associated. When pushing something
inbetween (in mkiv) it ends up directtly in the list. This is the
default because otherwise users will wonder why spacing might get
messed up (due to an unseen but present node). It is possible to
force a location by explicitly setting \type {location} to \type
{here}.
Another way to force a certain order is to set the \type {order}
variable when placing a list. The \type {command} option only
pushes commands into the right order, and \type {all} orders all
entries (which might be too much). In this case no specific
location is needed with the inbetween method. Maybe additional
mechanisms show up some day.
\subject{normal} \placelist[testlist]
\subject{command} \placelist[testlist][order=command]
\subject{all} \placelist[testlist][order=all]
\page \input tufte
\writetolist [testlist] {1} {One}
\writebetweenlist[testlist] {\blackrule[color=red,width=\hsize]}
\writebetweenlist[testlist][location=here]{\blackrule[color=blue,width=\hsize]}
\writetolist [testlist] {2} {Second}
\writetolist [testlist][location=none]{W} {Whatever}
\writebetweenlist[testlist] {\blackrule[color=green,width=\hsize]}
\stoptext
I admit that it's not an easy mechanism but any default would at some
point trigger complaints. So it probably needs to be wikified.

Thanks for this. It's been wikified in the reference wiki:
