That will be true if $start_line is true and false if $start_line is false. The value in $end_line is irrelevant.
perl -lne 'print if 10..20' some_file
prints lines 10-20. See the perlop manpage.
Re-read it. Using .. that way ONLY WORKS if its arguments are constants.
You're right. Somehow I've never run across that in the years I've been using perl. I tested with constants and then tried to generalize it in my response without testing. Sorry for the mis-info.
