Often it is best to have an entire paragraph about the characters present in a room, but suppose we're narrating a large party with a lot of people moving around. In that case, it might be better to list everyone together, then add a few salient details by way of follow-up, like this:
say "You can see [a list of people who are marked for listing] here. ";
repeat with named party running through people:
now the named party is not marked for listing;
let count be the number of visible other people who are carrying something;
if count is 0:
say paragraph break;
continue the action;
let index be count;
repeat with holder running through visible other people who are carrying something:
if index is count, say "[The holder]";
otherwise say "[the holder]";
say " has [a list of things carried by the holder]";
decrement index;
make delimiter index of count.
The next part could be simpler, but for rigor we will write it in such a way that it will work whether or not the serial comma is in use. This requires some extra work.
