The problem is that you need to get
my $regex2 = qr% \n
(?:
\QI'll be good.\E
| Hushing
| Hrumph
| \Q>:[\E | \Q:-(\E | \Q:(\E | \Q:-c\E | \Q:c\E | \Q:-<\E | \Q:<
+\E
| \Q:-[\E | \Q:[\E | :\{ | \Q:-|\E | \Q:@\E | \Q>:(\E | \Q:'-(\
+E
| \Q:'(\E
| \QShutting up now.\E
| \QBut, but...\E
| \QI'll be quiet.\E
)
%mix;
But, as curly braces are the delimiters, qr{ \{ } turns into qr% { %', , but there's no way how to express 'qr% \{ % with curlies as the delimiters - but you don't need that, as they're equivalent.
That's why I don't like using curlies as regex delimiters.
#!/usr/bin/perl
use warnings;
use strict;
use feature qw{ say };
my @res = ( qr% a{1 %,
qr{ a\{1 },
qr% a\{1 %,
qr% a\Q{\E1 %,
qr{ a\Q\{\E1 },
qr% a{{1}1 %,
qr{ a\{{1}1 },
qr{ a\{{1}1 },
qr{ a\{\{1\}1 },
qr% a\{{1}1 %,
);
say $_, ' a{1 ' =~ $_ for @res;
Update: more examples in the second code.
