Regexes in Perl 6

 operator.

use v6;

my $text = "Learning regexes";
if $text ~~ m/ regex / {
    say "This is about regexes!";
}

if $text !~~ m/ foobar / {
    say "No foobar in $text";
}

Regex in Perl 6 disregard spaces by default. People who are used to the Perl 5 style regular expressions - which means basically every programming language that has a regular expression library - will usuall think as spaces being significant in the regular expressions. We will have to unlearn that and think about the individual bits and pieces that are the tokens we would like to match. Basically Perl 6 regexes work as if you always had the /x modifyer on which in Perl 5 means disregard spaces and treat # as start of comment.
