It's rather unfortunate that the tuple needs to be unpacked at all.

Instead, it should be possible to simply pass the address tuple
directly to the socsket.getaddrinfo() function, and let it worry about
the tuple-ness of the address, raising exceptions accordingly.

The socket.getaddrinfo() function, unlike every other python socket
function, takes separate host and port parameters. Which forces every
user of the socket.getaddrinfo function to do the same unnecessary and
potentially error-prone address tuple unpacking.

I have raised a feature request to change this.

[1685962] socket.getaddrinfo() should take an address tuple.

Alan.
