--- Comment #10 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
i already started on this and the budgets are correspondingly not balanced 
given that i have already done the majority of the work already
(see TODO list, 80% completed).

again this is another task that i allocated a budget for based on
one person (me) doing it. i am not sure what to suggest here as it
has been too long since i looked at this but it should be straightforward
to examine how the LD/ST-Immediate unit tests work and get the
corresponding LD/ST-Indexed ones running, at which point doubly-linked
lists can easily be done as well (double-chasing by two-overlap
LD/ST-Update).

it is much more straightforward than the Vector-Immediate task,
and examination of the commit-diffs will show clearly what was done.
