specifying address family before establishing connection

[Brane F. Gračnar]

Hello ;)

I'd like to specify address family before issuing TCP connects.  I have a list 
of hostnames, both accessible via ipv6 and ipv4.

I'd like to connect to some of them using only ipv6 and to some of them using 
only ipv4.

Is it possible to achieve this just by setting $ENV{PERL_ANYEVENT_PROTOCOLS} 
before calling tcp_connect()?

What about AnyEvent::HTTP?

Cheers, Brane
