The variable quantity coming before the constant.

Why? Surely they have equal relevance?

Yes, perhaps logically and mathematically, but psychology and
linguistics
are not logic and maths. Where I live, a native English speaker is
much, much,more likely to say things like, "If the door is open ..."
or "If the outside temperature is below 20 degrees ...", compared to
"If 'open' is the state of the door" or "If 20 degrees is greater
than the outside temperature".

For the first, in C we say if(is_open(door)), so it's beside the
point. The second isn't expressing an equality relationship, that's
beside the point too.

(I wonder: if you write equality expressions as "2 == x", do you
also, for consistency, write code like "0 != x" and
"for (i = 0; sizeof chararray > i; i++)"?)

(a) Those aren't equality expressions. There is no !== operator, no =>
operator, no risk of accidentally assigning instead of comparing;
(b) I see no logical difference between x != 0 and 0 != x, so I don't
understand the point you're trying to make.
