Perl Style: Avoid Symbolic References
-
Beginners often think they want to have a variable contain the name of a variable.
$fred = 23; $varname = "fred"; ++$varname; # $fred now 24
-
This works sometimes, but is a bad idea. They only work on global variables. Global variables are bad because they can easily collide accidentally.
-
They do not work under the use strict pragma
-
They are not true references and consequently are not reference counted or garbage collected.
-
Use a hash or a real reference instead.
Forward to Using A Hash Instead of $$name
