OK, so now the correct incantation should be: 

unshift @INC, sub {
    my ($self, $name) = @_;
    
    # load the module first
    local @INC = grep { !ref($_) || $_ != $self } @INC;
    require $name;

    # add logging to the package

    # ignore this hook
    my $line = 0;
    return sub {
        unless ($line++) {
            $_ = "1;\n";
            return 1;
        }
        return 0;
    }
};
