8.166 vars

Pragma that, given a list of variable names, predeclares all variables in the list, making sure they are available to routines whose loading is delayed (e.g., routines that are loaded by the AutoLoader or SelfLoader). This allows you to use the variables under use strict . The vars pragma also disables warnings about typographical errors.

use vars qw($var1 @var2 %var3);
