but there is a warning that it is experimental and there is no hint as to how to implement it.

Actually, if you keep reading, the perldoc on Getopt::Long, it tells you how to use that feature.

From the perldoc:

This can be accomplished by adding a repeat specifier to the option specification. Repeat specifiers are very similar to the {...} repeat specifiers that can be used with regular expression patterns. For example, the above command line would be handled as follows:

GetOptions('coordinates=f{1,}' => \@coor, 'rgbcolor=i{3}' => \@color);

Taking your example code and input, I tested the following code:

use strict;
use warnings;
use Getopt::Long;

my @list;

my $getoptresult = GetOptions('list=s{2}' => \@list);

foreach my $item (@list) {print "$item\n";}

Being on Windows, I had to use a double-quotes instead of single-quotes, but here's how the script was called:

perl test.pl --list "strA,==,100" "strB,>,1000"

Here's the output:

strA,==,100
strB,>,1000

You'll want to look at the perlre perldoc for more details on what else you can use in "{...} repeat specifiers". In my code, the {1,} is telling Getopt::Long that @list is getting one or more elements.
