Yeah, I always forget which is fd 0 and which is fd 1 too.

Having nice descriptive names rather than using numbered indexes is 
generally better practice, and I don't think there is any serious 
downside to using a namedtuple. A minor enhancement like this shouldn't 
require an extended discussion here on python-ideas.

Jonathan, would you be so kind as to raise an enhancement request on the 
bug tracker? I don't think it's too late for 3.5.
