That's a good piece of rather in-depth discussion ;). And this is the first time that I understood the subtle workings of the range operator. It's really a 'flip-flop' kind of an operator. Here's the way I'd use it:
-----------------

#!/usr/local/bin/perl -w
use strict;

# TEST for '..' (and '...') operators
#
# Description of the range operator is found
# at the END of this file.
#

print "TEST 1: Skipping perldoc comments.\n----------------\n";

while (<DATA>) {
    next if (/^=head/ .. /^=cut/);
    print $_;
}


__DATA__

# pretend this is a config file
var = 0;
var1 = 0;

=head
this should be skipped by
the /^=head/ .. /^=cut/ range
operator.

=cut

var2 = 0;

-----------------

Your example with data is also very neat one. I guess one could use the range operator with special objects that serve as data iterators (say, list iterators etc.)

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
