Yeah, $self->test will work (altho this still does not require a constructor for One, seems like a red herring):

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

{ package One;
  sub test {
    my $x = pop;
    print "$x\n";
  }
}

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

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

I guess this is starting to seem a little finnicky, but I would like to use test() as if it were a function internal to Two, not requiring an object.

Basically, I have two classes that share a bunch of such internal functions (no object required, it's just string parsing), so I thought the best thing would be to have a base class containing those.

In fact Exporter does work, see my reply to jethro.
