Re: Simple inheritance question

If test() were included in Two's namespace, Two could not override it with its own test() if needed.

UPDATE: You can use Exporter to add test to Two's namespace if you like. After all a class is just a package

Yeah, that does it: `#!/usr/bin/perl -w use strict; { package One; use Exporter; our @ISA = qw(Exporter); our @EXPORT = qw(test); sub test { my $x = pop; print "$x\n"; } } { package Two; use base "One"; sub new { One->import; my $self = {}; bless($self); } sub eg { test(pop); } } my $obj = new Two(); $obj->eg("hello");` [download] Thanks all!

#!/usr/bin/perl -w  
use strict;

{ package One;
  use Exporter;
  our @ISA = qw(Exporter);
  our @EXPORT = qw(test);
  sub test {
    my $x = pop;
    print "$x\n";
  }
}

{ package Two;
  use base "One";
  sub new {
    One->import;
    my $self = {};
    bless($self);
  }
  sub eg {
    test(pop);
  }
}

my $obj = new Two();
$obj->eg("hello");
