Long enough ago that if you find a Perl on which
perl -le " foreach (0..100_000_000) { print } " | more
has a seg or heap fault immediately, you've got a disturbingly old Perl.
Really old Perl documentation warns against doing this, but eventually
Larry made the range operator in list context when it was specifically
a foreach optimize to a lazy list internally when over some threshold
in size.
A quick scan of recent perldelta files doesn't turn up "range
operator" in this context, only in other things.
