     href="http://perl6.org/">Perl 6</a> working thanks in part to to

+Here is an example stored procedure written in PL/Perl 6, from our test suite:
+
+<pre>
+CREATE OR REPLACE FUNCTION test_fibonacci_plperl6(integer) RETURNS int LANGUAGE plperl6 AS $$
+my $limit = @_[0];
+[+] (1, 1, *+* ... $limit)
+$$;
+</pre>
+</p>
+<p>
+The first line is SQL, and everything between the $$ symbols is Perl 6! This stored procedure takes a single integer N and returns the sum of the first N Fibonacci numbers.
