I have two files:

# inc.pl
use vars qw($foo);
$foo = "hello";
1;
[download]

# t.pl
use strict;
use vars qw($foo);
do 'inc.pl';
print $foo, "\n";
[download]

If I remove the 'use vars' from t.pl than t.pl fails to run with the error 'Global symbol "$foo" requires explicit package name'. How can I create a main:: global variable in inc.pl which I can access from t.pl without explicitly listing it in a 'use vars'?

I would like to have lots of variables in inc.pl without listing each of them in files that use them.

Thank you for any help.
