Note! This site is about Perl 6.
If you are looking for a solution for Perl 5, please check out the Perl 5 tutorial.
We are used to the shortcut opertators from many languages.
They change the value that would have not been changed by merely participating
in an operation.
my $num = 23;
say $num + 19; # 42
say $num; # 23
$num += 19;
say $num; # 42
The Perl 6 Tricks and Treats newsletter has been around for a while.
If you are interested to get special notification when there is new content
on this site, it is the best way to keep track:
This is a newsletter temporarily running on my personal site (szabgab.com) using Mailman,
till I implement an alternative system in Perl 6.
