I will briefly, because I think we're really subjective territory, and
I'm not sure how well I can explain myself, or even if it'll be very
elucidating if I do:

Really, this is the bit that I don't agree with - and I think its how
our minds have respectively come to read code, that I can't read that
line of code in your sense without it feeling unnatural to me.

Don't really understand why.  I think possibly part of it is that
something in my mind is seeing the right-hand-side as "true" rather than
1 - and as soon as I think "Boolean" I'm right into thinking about
predicates and conditionals.

When you read some prose, say, that you consider well written, your mind
parses the meaning and the poetry out without you ever consciously
thinking about the words.  But if an author uses a clunky conjunction,
or just an idiom with which you're insufficiently familiar -- clearly
the best analogy here -- (or just outright writes a few sentences in
Spanish, thank you, Cormac McCarthy) you're jerked right back into the
text to try and figure out what was intended.

There's something about the implicit conversion from "true" to
"1" that requires a tiny extra element of conscious thought that
prevents smooth comprehension.

Does that make even the slightest bit of sense?

(Told you it'd be unhelpful.)
