With my $substitution = 'Goodbye \1'; which is obviously not a regex, which regex "group" are you back-referring to?

Check this however: 

my $string = "Hello sailor";

my $regex  = qr/Hello (.*)/;

$string =~ s/$regex/Goodbye \1/;

print "string is now $string \n";

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
