Open4 in standard library?

Hello

(Sorry for any duplicate messages, I sent this yesterday and it didn’t
seem to reach the list…)

I was wondering if Ara’s open4 extension could be considered for
inclusion in ruby’s standard library, or if the same solution used to
return the exit status could be used in open3. Open3.popen3 is a bit
annoying in that it doesn’t set $?, or return the status somehow.

Best regards,
Andre
