$ ls -l /usr/share/perl5/Debconf/Question.pm
-rw-r--r-- 1 root root 5867 Oct 1 04:39 /usr/share/perl5/Debconf/Question.pm
$
$ grep -A1 -B1 '(\\\\)' /usr/share/perl5/Debconf/Question.pm
my $escape;
while ($rest =~ m/^(.*?)(\\)?\$\{([^{}]+)\}(.*)$/sg) {
$result.=$1; # copy anything before the variable
$
