How so? Equality is a symmetric property. (foo == bar) means exactly
the same thing as (bar == foo).

If this kind of difference trips you up, you are not really reading
the code properly for its semantics.

If you're not really reading for semantics, you will not find errors.

In any case, code which follows a convention in this regard can reasonably
be expected to be *consistent*: to do it the same way everywhere.

So if you want to be able to tune out and unconsciously pass your eyes over
code, so that only strange-looking construct generate an alert,
that just requires a bit of re-training for this reversed convention.
