I often use join but it can begin to get tedious if, for instance, you are printing more than one array using the same separator. Localising a change to the list separator then begins to simplify things, as in this rather contrived and silly example.

use strict;
use warnings;

my @ladies = qw{ ann flo jen };
my @gents  = qw{ bob pip tim };

print
   q{The ladies, (},
   join( q{, }, @ladies ),
   q{), met the gents, (},
   join( q{, }, @gents ),
   qq{).\n};

print
   qq{The ladies, (@{ [ join q{, }, @ladies ] }), },
   qq{liked the gents, (@{ [ join q{, }, @gents ] }).\n};

print do{
   local $" = q{, };
   qq{The ladies, (@ladies), married the gents, (@gents).\n};
   };
