Pragma that, given a list of variable names, predeclares
all variables in the list, making sure they are available to routines
with delayed loading (e.g., routines 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);
