Still Use local() 1. You need to give a global variable a temporary value, especially $_, 2. You need to create a local file or directory handle or a local function, 3. You want to temporarily change just one element of an array or hash Pass by Reference Prototypes Constant Functions Overriding Builtin Functions Autoloading SEE ALSO perlmod - Perl modules (packages and symbol tables) DESCRIPTION Packages Symbol Tables Package Constructors and Destructors Perl Classes Perl Modules SEE ALSO perlmodlib -
