Hi
Surely in this case one wants stdout in a separate String to stderr?
If something fails in the middle of a long operation, I want just the error, doc!
Sometimes what you want is the ordered sequence, so you can see which out message came just before the err message. You could just generalise to: IO (ExitCode, String, String, String) where ( _, out `intersperse` err, out, err) But that feels a little ugly
How about two separate versions? In which case, what should they be called?
The current proposal feels very good. You have the "I expect it to fail" and the "I expect it to succeed". If you introduce another variant, it suddenly becomes much less clear. Thanks Neil
