doesnt that mean you will need to fix all of the users of the function?
with my net/http example above you can somewhat control it.

but e.g. ruby -r open-uri 'p open("http://[::1]:8080/test/test")'
doesnt give me control over which function is used.

i think the better approach might be to let url.host return "::1".
and just encode it when constructing a new url.

another option might be monkeypatching the string object returned by
url.host and add a "dnssafe" method like shown in the msdn article.

then the resolv class could get the dnssafe version when needed. but it
still might lead to trouble when the hostname is passed to other C
extensions.
