Actually, it's more than just a boolean: it returns a counter number for
each time it evaluates to true, with an "E0" appended if the second
condition is true, i.e. the last time. That counter is then reset for
the next run.
for (1 .. 19) {
$result = $_%5==0 .. $_%3==0;
print "$_ -> $result\n" if $result;
}
-->
5 -> 1
6 -> 2E0
10 -> 1
11 -> 2
12 -> 3E0
15 -> 1E0
Note that the three dots operator, "...", will behave differently in
this last case.
