Re^3: How to export a package sitting lower in a module?

Sometimes (especially if you have an object-oriented project, with many little packages), it's not convenient to have each package in a speparate file.

If you are doing OO programming in Perl, you don't need to import anything. Using packages as libraries and exporting subroutines into a user space is actually a direct contradiction with a rigid OO model.

Please note that this still doesn't work: the .pm module fails, complaining that the second @ISA is a bareword.

That's because you're violating strict. Try our:

package pack_B;
use strict;
require Exporter;
our @ISA = qw {Exporter};
our @EXPORT = qw {third fourth};
sub third {
}
sub fourth {
}
1;

Thank you, kennethk. That works (provided that you use "our @ISA" and "our @EXPORT" both in the first (pack_A) and the second (pack_B) packages). Many thanks - Helen	[reply]
