It looks like plperl_convert_to_pg_array() calls that Perl function
to convert a Perl list reference to the string representation of
PostgreSQL array, so functions like this can work:

CREATE FUNCTION foo() RETURNS integer[] AS $$
return [1, 2, 3];
$$ LANGUAGE plperl;

SELECT foo();
   foo   
---------
 {1,2,3}
(1 row)

But this example crashes the backend if plperl.use_strict is enabled :-(
