Then how would the following ever work:
xxx=$(date)
( sleep 5
xxx=$(date)
echo $xxx
) &
echo $xxx
if $xxx were coerced when the (...)& is being scanned, then the two echo statements would always show the same time but they don't (you can try it). Are you suggesting that $$ is coerced by different rules than $xxx?
