Or you use the [CountOf secret operator][1] to count the number of
items split returns, but not well the use of a -1 limit on the split.
If you don't provide a negative limit, then split will optimize itself
for returning to an empty list and the result will be 1 regardless of
the input (well, an empty string will still return 0).
xpto( ()= split /\n/, "first\nsecond\nthird", -1 );
