NetAddr::IP's use of $& and $`

[Daryl C. W. O'Shea]

Hi Luis and Michael,

Would you be able to consider reworking NetAddr::IP to avoid the use of, 
or loading of anything that uses, $& or $` so that the huge speed 
penalty imposed by Perl when doing so can be avoided?

NetAddr::IP is used by Mail::SPF which is used by Mail::SpamAssassin. 
Apache SpamAssassin needs to avoid the speed penalty imposed by $& and 
$` at all costs.

Please see SpamAssassin bug 5312 for some background on this:

Thanks!
