Subject: [ruby-core:64726] Re: [ruby-trunk - Feature #10181] [Open] New method File.openat()

We already have opendir (in the form of Dir.open), so would
Dir.at would be an alias of Dir.open?

I do not like aliases since they makes reading/searching code harder.

But I think we should use Dir.open instead of File.open/File.new for
openat, and also support Dir#fileno:
