What does PL/Perl 6 look like? Here is a nice example of a PL/Perl6 function which calculates the sum of all Fibonacci numbers <= 100: CREATE FUNCTION test_fibonacci_plperl6(integer) RETURNS int LANGUAGE plperl6 AS $$ [+] (1, 1, *+* ... 100) $$; You will notice three spiffy new Perl 6 operators in there, the summation operator [+], the new range operator ... (which used to be .. in Perl 5), and the *+* operator. What exactly is the *+* operator? pmichaud++ jokingly referred to it as the "cheerleading plus", but it is actually just a plain old infix "+" operator, sandwiched by two "*" (a.k.a Whatever) operands. It basically takes the previous two elements in a list, sums them together and returns the sum, which is exactly how the Fibonacci sequence is defined. -- Diego Saravia [email protected] NO FUNCIONA->[email protected]
