My problem is easier to show than explain. I have three files:

The main script: 

# main.pl
use Bar;
use Foo;
Bar("Called from main");
&Foo();

[download]
And two secondary scripts: 
# Foo.pm
package Foo;
use Exporter;
@ISA = 'Exporter';
@EXPORT = qw(Foo);
use strict;
sub Foo { Bar("Called from Foo"); }
1;


# Bar.pm
package Bar;
use Exporter;
@ISA = 'Exporter';
@EXPORT = qw(Bar);
use strict;
sub Bar { print "$_[0]\n"; }
1;

[download]
If I run them, I get this output: 
Called from main
Undefined subroutine &Foo::Bar called at Foo.pm line 7

[download]
Inserting a use Bar; within Foo clears up the problem. But since main already uses Bar, shouldn't Foo pick that up as well? What am I missing?

A fair fight is a sign of poor planning.
