in thread Foo is not a Bar, why?

That's all good and dandy, but even tough your module looks useful (and generic), I can't say I like the resulting interface — i.e. the use statement. I'd rather see something like this:

use strict; package Foo; use isa qw(Bar); sub new { bless {},shift }

The module isa.pm can actually quite short:

# file isa.pm package isa; sub import { my $pkg = shift; my $caller = caller; no strict 'vars'; push @{"$caller\::ISA"}, @_; } 42;
Et voilà:
foo is a Bar

Of course, with base doing the same and more, I don't know if there's much need for this here module.
