Just need to use 'our'.  'vars' is old skool for 'our' (well for variables 
in the current package anyway)

    (via "perldoc vars")
    NOTE: For variables in the current package, the functionality provided
    by this pragma has been superseded by "our" declarations, available in
    Perl v5.6.0 or later.  See "our" in perlfunc.

These do the same thing...

    use vars qw/ $opt_size @opt_sizes $opt_bar /;
    our ($opt_size, @opt_sizes, $opt_bar);

Darth Vader says, "Nooooooooooooooooo!!!" :P

Also its almost generally a very bad idea to remove 'use strict;'
Very bad things are bound to happen without you being the wiser :)
