Is that forwards first or backwards first? (Re: unintuitive for-loop behavior)

Yep, part of the baby's hardware. Also, the interface is not limited to visual and auditory information:

You say tomahto, I say tomarto. It sounds like we're using different language
to describe the same thing.

Babies do have an instinct to suck if you stick a nipple (or a finger) in their
mouth, or even if you merely touch them on the lips or cheek:

The rooting instinct, together with the sucking instinct, is present in all
healthy babies. I would expect that only the most severe development
abnormalities would prevent instincts as important for survival as these two.

Between the rooting and sucking instincts, I consider "the only intuitive
interface is the nipple" is correct. However, that doesn't necessarily mean
that babies will suckle well: there are all sorts of reasons why babies don't
breast-feed well, e.g.:

Of course the instinct isn't *visual* -- babies may not open their eyes for
many minutes after birth (one study found that about 3% of babies hadn't opened
their eyes within 20 minutes, the maximum time allotted) which may be long
after their first suckle.

Nevertheless, there are senses other than sight.

git gets easier once you get the basic idea that branches are homeomorphic
endofunctors mapping submanifolds of a Hilbert space.
