Sorry I sent the response individually by mistake, here the same comments.

I agree with you. I will put it on the next version.

Currently we have more IPv4 than IPv6 however I'm not sure if this will be other way around in 5 years later. I am thinking, however, it is better to make default behaviour IPv4 because intranet would use it and it can hold compatibility with other script. (only my expectation). Any idea?

I will add it.The condition type I am a little bit hesitating to add. If it is better to suggest what to have, I would say '&socket' as a base condition type and the rest of detail sub conditions are implementation dependent.

Yes, I will add it.FYI, if 'proc' returns then it returns the result of given 'proc' and socket will be automatically closed. If 'proc' doesn't return then given socket won't be closed automatically. It's analogy of 'call-with-port'
