The dot operator combines two strings. So given:

my $t = "apple";
my $u = "banana";

my $x = "Combined: " . $t . $u . "\n";

Perl starts to combine the strings:<\p>

my $x = "Combined: " . $t . $u . "\n";            # before we start
      = "Combined: " . "apple" . "banana" . "\n"; # expanded variables
      = "Combined: apple"      . "banana" . "\n"; # combined first two
      = "Combined: applebanana"           . "\n"; # then the next
      = "Combined: applebanana\n";                # then the last
