You shouldn't use them for ipv4 either.  You should use ip prefix lists (or
non regexp-based bgp communities if your bgp policy is anything more than
trivially complicated) for controlling prefix distribution instead.
as-path lists are incredibly inefficient and can spank your router's route
processor CPU.
