Hi, this is probably very simple, but my brain is starting to smoke because I just can't find what I'm doing wrong. I want to make Fiets::Cache an inherited class of Cache::Cache (I want to do some extra stuff in the get and set functions), so I wrote this constructor: 
package Fiets::Cache;
use strict; use warnings;
...
sub new {
    my ($self,$class)=@_;
    my $cdir =  Fiets::getvar('cachedir');
    if ($cdir) {
        use Cache::FileCache;
        use base qw(Cache::FileCache);
        $self=Cache::FileCache->new({
            'cache_root' => $cdir,
            'default_expires_in' => '4 h'
        });
    } else {
        use Cache::NullCache;
        use base qw(Cache::NullCache);
        $self=Cache::NullCache->new({
            'default_expires_in' => '4 h',
        });
    }
    bless ($self,$class);
    return $self;
}
...
1;

This code is called from Fiets.pm like this: 
use Fiets::Cache;
our $cache=Fiets::Cache->new();

Fiets.pm and $Fiets::cache are used in my main-program, and other libraries in the Fiets::-hierarchy.

Now my problem: Calls like $Fiets::cache->get($id) in other libraries will return errors (via an Exception-handler) like: 
'Can\'t locate object method "get" via package "main"'

If I change the two-argument bless into bless($self), these errors disappear and in the debugger I can see (with 'm') that my Fiets::Cache indeed has its own new method and a couple of other methods of it's own and inherits a whole bunch of methods for Cache::Cache.

But I still don't know why the two-argument bless will not work for me. This must be something stupid and simple I guess.

PS: 'Fiets' is just a hypothetical name.
