Well I tend to avoid such side effects because of this experience.

hum? We use the side effects of putting the actual scalars on the stack all the time (e.g. $x = 3;). I presume you mean you avoid using writing to the scalar twice in the same statement, and avoid writing to the same scalar twice in the same statement.

The thing is, @a, @a=() doesn't do that, at least not any more than splice(@a) or shift(@a) do, and I'm pretty sure you don't avoid those.
