Perl DBI atomic fetch

When getting a single row of data from a database table is desired, using atomic fetch makes life a lot easier, for example (assuming $dbh connection is established)
Example 1:

my ($name, $country) = $dbh->selectrow_array( "SELECT name, country FROM tbl_customer" );
print "Customer $name is from $country.\n";

Example 2:

my ($cnt) = $dbh->selectrow_array( "select count(*) from tbl_customer");
print "There are $cnt record(s).\n";
