but with value FALSE if any list element isn't finite. Is this intended?
That is not the pattern, and the real pattern *is* intentional. All
non-numeric vectors are not finite:
 FALSE FALSE FALSE
Although a list is a generic vector, it is not a numeric vector.
I'll add that comment to the help page.
