As a term of art, its definition as you state it I cannot dispute.
As a term of common English, a "side" effect is something different from the
stated, explicit purpose.
In medicine they say, "There are no side effects, only effects."
I should have used the term of art, but I was actually saying "side effecty",
not "side effect", even to including the quotes, so I explicitly avoided the
term of art.
I admit I should have used a clearer term, but I was using the term introduced
in the post to which I responded.
My point is that assignment isn't a "side effect" (ordinary English) of
auto-increment, but the intended effect. In the context of why assignment and
its siblings can constitute a statement, but not '?:' or '+', it makes sense.
Thank you for distinguishing this from the term of art.
