I don't know If I understood well, but did you try this?
when
$xs : ArrayList() from collect(X())
$total : Number() from accumulate(X($c: count), sum($c))

Yes, that was the solution I happened on, but I wanted to make sure that
this wasn't doing unnecessary duplicate work. To my naive eyes, it looks
like two "from"s result in duplicate work. I take it that's not true?
