Hi Stuart,

Ok. Enough to hold the spec a bit longer and make more modifications
to fix the problem? (just asking)

Same here, but as you said, that's not an option (too bad).

Dereferencing the list I don't think is technically possible. You
would instead need a 'for' loop and call highlight with each item, but
them you run into timing issues. Create a list on the fly makes more
sense in my opinion.

Exactly.

As I said above, I don't think it's doable without a 'for' loop.

No, see above (or at least, I don't know how to do that).

That's correct.

True.

Forget I said that for now... that's an implementation hurdle.
Although they are important, let's look at it from a user perspective
for now.

:-) Ugly as you said. That's what users would have to do if we leave
the spec like it is.

What do you think of the option of having two highlight method (ex:
highlightOne (takes a single APS), highlightMany (takes a list of
APS)?
