8.232. vars
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);
