Re^4: How to export a package sitting lower in a module?

[HelenCr]

Corion: note that the two packages are sitting in the same module file.
Like I said, it's not straightforward to export from a package which sits lower in a module. Please try to run this module: it doesn't work - it gives errors:

# Name of this file: pack_A.pm
package pack_A;
use strict;
require Exporter;
@ISA = qw {Exporter};
@EXPORT = qw {first second};

sub first {
}
sub second {
}
1;
#end package pack_A;

package pack_B;
use strict;
require Exporter;
@ISA = qw {Exporter};
@EXPORT = qw {third fourth};
sub third {
}
sub fourth {
}
1;
#end package pack_B;
#end of file pack_A.pm

with the main script:

use pack_B;
# or use pack_A; ?
third();
