in reply to base class manipulation: Is there something similar on CPAN?

You want a module that pushes onto an array?

I would do: 

package LWP::UserAgent::Powerfull;
use LWP::UserAgent::Proxified;
use LWP::UserAgent::Determined;
use LWP::UserAgent::Cached;
our @ISA = qw[LWP::UserAgent::Proxified LWP::UserAgent::Determined LWP
+::UserAgent::Cached];

Or, if for whatever reason, you insist of having the indicated chain: 
package LWP::UserAgent::Powerfull;
use LWP::UserAgent::Proxified;
use LWP::UserAgent::Determined;
use LWP::UserAgent::Cached;
push @LWP::UserAgent::Determined::ISA, "LWP::UserAgent::Proxified";
push @LWP::UserAgent::Cached::ISA, "LWP::UserAgent::Determined";
our @ISA = "LWP::UserAgent::Cached";

assuming that LWP::UserAgent::Proxified already inherits LWP.

    Your second example looks more correct, but in fact should be: 
    foreach my $parent (@LWP::UserAgent::Determined::ISA) {
    if ($parent eq 'LWP::UserAgent') {
        $parent = 'LWP::UserAgent::Proxified';
        last;
    }
}

    instead of push.
    Module can automate this routine actions and make some additional checks.
