Perhaps render-list should allow item-nr (or some other variable) to
point to the name of the counter and not presume that the counter is
always called: item
Working from that I will see if i can use a <with to override <item>
and maybe get things to work a little faster that way.

The problem seems to be to the storage and recall of the counter.
<with|...|item-nr|<value|pob>|

<render-list|<arg|body>>
...
<assign|pob|<value|item-nr>>

If I don't save the item-nr in pob, OR if I initialize the item-nr to
a literal number, then updates are fast.
Otherwise, on large documents, entering a new line in the custom list
can be painfully slow (unless I press shift-enter so that <item> is
not created).
Does any master have information on how saving AND recalling a counter
from a global variable could cause this slowness? My guess is some
magic that might be avoided perhaps with some sanitising lambda

I've pinned the problem down to the assignment of item-nr. Each named
code-chunk can appear in multiple chunklets and has it's own line
counter that is shared across all chunklets, so I assign item-nr to
contain the counter-so-far before I render the list. (BTW I wish html
export also recognized that item-nr may not start at 1):
Assigning item-nr as shown below makes things slow.
<with|...|item-nr|<value|<merge|code-line-|<value|nf-name>|-nr>>|

<render-list|<arg|body>>

Alternatively, if item-nr is assigned to a literal numeric value,

I expect I need to do magic with eval and quasi and so on, but no
amount of guessing has worked yet. I think I know that <with...>
encloses all assignments in <quote> so I tried using <assign> instead
with various incantations of quasi and eval but without success.
I need a master to give me a tip on this.... how can I early evaluate
<value|<merge|code-line-|<value|nf-name>|-nr>> to become a numeric
value?
