Hmm,

What if the user entered m/foo/x when asked for a regex? Technically, the regex the user wanted was foo, but they entered the whole match command instead: 

my $keywords = "NSA|cocaine|Lybia|assasin(at(ion|e))?|CIA";
print "Enter regex matching other keywords:";
my $userwords = <STDIN>;     # user enters "m/MI-6/x"
if ($string =~ m/$keywords|$userwords/x) {
  print "Found a terrorist!  $string\n";
}

Obviously, m/MI-6/x (they want to match "MI-6", not "m/MI-6/x"). How could that be corrected for?
