For negating all elements of an array:
@negatives = -� @positives;

The above example is in S03, so that is not an option.

You understand it. I understand it. But how does the parser know the
difference between
@x = -<< @y;
and
@x = [+] @y;
or even
@x -= @y;
which shows that the position of metaoperator is not the distinguishing
factor.
