I definitely prefer to use, and promote, the explicit names “stdin”,
“stdout”, and “stderr” rather than the file descriptor numbers.

On the point of confusing them though: I find it easy enough to remember
that the two streams for output stay together, and the input one comes
first at 0.

+1, let's just get the standard names there as attributes of a
namedtuple.

One more set of magic numbers to relegate to implementation detail,
encapsulated where they belong!
