Can someone please explain the regular expression with the tilda?
What is being matched there?
Thanks for your help.

$trap++ if($st_domains =~ /~$user~/i);
$trap++ if($st_domains =~ /~$tld~/i);
$trap++ if($st_users =~ /~$user~/i);

Why do you ask? Is there any reason to believe that a '~' would match
anything but a '~'?

To find out which characters are special in Perl regular expressions:

perldoc perlre

(Another thing is that a tilde both before and after e.g. a username
appears odd to me.)
