I expect that these functions taking a *named* parameter "x" is an accident that
shouldn't be relied on.

OK, so I'd say the filtering would follow any changes made to some_seq

My intuition is that the lambda creates a closure that captures the
value of some_seq. If that value is mutable, and "modify some_seq"
means "mutate the value", then I'd expect each element of seq to be
tested against the value of some_seq that is current at the time the
test occurs, i.e. when the
