Time::HiRes
I notice in the Links SQL code you use:

BEGIN { eval { require Time::HiRes; import Time::HiRes qw/time/; }; }

I've always used:

use Time::HiRes qw(time);

Is that wrong or is there a difference?

I was thinking more in terms of this bit:

import Time::HiRes qw/time/;

Is that because you need "require" for eval and you can't use qw(time) with require?

Yep.

From Perl in a Nutshell:
use Module list
use version
use Module version list

and

require filename
require num
require package

Hi,

use Foo 'bar';

is equivalant to:

BEGIN {
require Foo;
import Foo 'bar';
}

Without the import, you wouldn't have `time` overidden.

Cheers,

Alex
