X and Y were meant to be placeholders for arbitrary subexpressions.

I prefer to treat (X==Y) as a mathematical formula (stating that
subjects X and Y have equal values), rather than shoehorn it into
an English sentence that has X, but not Y, as its subject.

How about Yodaness when both operands are non-constant, as in
(sin(alpha) == cos(beta)) ?.
Would it now matter which operand goes on the left side?

What if it's unknown which of the operands is constant?
Consider the expression (pNeedle == pHaystack).
If we assume that pNeedle is variable and pHaystack is
constant, this expression is, supposedly, perfectly readable.
But if it turns out that pNeedle is constant and pHaystack is
variable, the same expression suddenly becomes Yoda? So Yodaness
is not a syntactic property of the expression itself, but also
depends on additional knowledge that may or may not be obvious from
looking at the expression and its context, and that even may change
at runtime?

I think the main purpose of the == operator is to test whether
two values are equal.  For that purpose it does not really matter
whether operands are constant or not: it's equality we're
interested in, not constness.  Taking constness into consideration
just complicates things unnecessarily; so let that not influence
the way equalities are notated.

By the way, does Yodaness apply to other commutative operators as
well? Which one of (2 * f(x)) and (f(x) * 2) is Yoda, and why?

It might help to re-phrase the question to one that is more symmetric
in its operands, e.g. "are ... and ... equal?".

In this case I'd prefer arr[i]. There is a longstanding tradition
in programming languages to write arr[i]. C allows i[arr], but other
programming languages don't. In mathematics notation one sometimes
writes 'arr' with a subscripted 'i' to the right, but I've never
seen that the other way around.

In contrast, the equality operator is symmetric both in mathematics
and in most (every?) programming language that I know of.

I'd prefer the first form because it's simpler.

Actually the Yoda form can be slightly more readable when the
function call has a long argument list, as in

  if (3 == scanf("%g %g %g", &latitude, &longitude, &elevation))

one can immediately see that the returnvalue of scanf is compared to 3,
because the 3 is close to the scanf, whereas in 

  if (scanf("%g %g %g", &latitude, &longitude, &elevation) == 3)

the 3 and the scanf are far apart.
