It is very ugly and it is not very error prone (who knows what changes in regexp syntax can be expected in perl 5.10.0). It is better either to use already mentioned quotemeta or to escape string with \Q and \E in regexp. Example: 

my $string = "some unsafe chars";

.... =~ /\Q$string\E/;

It is exactly equivalent to 

my $string = "some unsafe chars";
my $temp = quotemeta $string;

.... =~ /$temp/;
