Reduction Triangle operators

Note! This site is about Perl 6.
If you are looking for a solution for the current production version of Perl 5, please check out the Perl 5 tutorial.

The ~ in front of the operator is only needed for the stringification of the list to inject spaces between the values when printed.

tutorial/arrays/triangle_operators.p6

#!/usr/bin/env perl6
use v6;

say ~[\+] 1..5;  # 1 3 6 10 15
say ~[\*] 1..5;  # 1 2 6 24 120

Output

tutorial/arrays/triangle_operators.p6.out

1 3 6 10 15
1 2 6 24 120
