OK. I'm stumped on this one.

I need to create a series of variables (with names like $db) which contain the values associated with their respective keys from the configuration module.

Here is what I'm trying to use; with the right side of that assignment replicating the syntax I'm already using repeatedly and successfully to extract data from my configuration hash. My question then is this: How do I set the variable name to match it without writing a dozen lines of repititious code here.

Update

shmem: or anyone really, if you have a real url for that article, that would be of interest to me. Thanks to all, a no strict refs; statement inside the foreach loop moved me past that one. I'm slowly refactoring a crudgy old but working cgi scripts' subroutines into module methods. Was trying to go the route of change only one thing at a time, ergo wishing to bridge how I coded two years ago before I discovered the wisdom of the monestary with how I code now, with a better understanding of objects and hashes. So far, that 300 line subroutine has served as fodder for one public and two substantive private methods, plus a couple of real short ones.

foreach my $config ('db','prefix','template','use_db','list_mail','sub
+_method','email_metho
d','debug_level','subscription_thanks_copy','campaign_type'){
      ${$config} = $supporters_conf::config->{$config};
  }

I'm seeing errors reading:

Can't use string ("db") as a SCALAR ref while "strict refs" in use at 
+/e6/run/cgi/supporters/MailingList.pm line 124.

All ideas are appreciated.
