Characters instead of regex patterns

[Jason Rauer]

Say I have:

foreach $string (@strings) {
if ($text =~ /$string/) { ... }
}

Now, it happens that the data in $string contains \|()[{$^*.? etc. that turn into regex metacharacters within m// but I want to match them by their literal value, not as a regex pattern. That is, now Perl terminates the script because whenever $string happens to contain, say, a ( it interprets it as an unmatched parenthesis in a regex pattern when what I'd like to match is just \(.

How to keep those characters from turning into regex patterns?

Thanks,

Jason
