Re: Cancel/no-op a require

Also, if you really want to use a hook in @INC, this is how they work...

unshift @INC, sub {
    my $module = $_[1];
    if ($module eq 'Foo.pm') {
        $INC{$module}++;
        my $line = 0;
        return sub {
            unless ($line++) {
                $_ = "1;\n";
                return 1;
            }
            return 0;
        }
    }
    return;
};

require Foo;  # no-op
