Nice! Hopefully one item on my feature-request list less soon. :-)

Ideally, it should allow all the "exact", "orlonger", "longer" etc.

Especially, it allows to use the same IRR-generated prefix list
to filter accepted prefixes from BGP customers (match exact), and use
the same prefix-list to accept more-specifics (match longer) for
remote-triggered blackholing or traffic engineering purposes and
treat them differently to the normal IRR-accepted prefixes.

Would be another step ahead IOS. :-)
