 For example L<Array> variables (C<@> sigil) empty themselves on list assignment, and then
 put all the values from the right-hand side into themselves. Contrary to item
 assignment, it means that the type of the variable on the left always stays
-C<Array>, regardless of the type of the left-hand side.

 Note that the item assignment has tighter precedence than list assigment, and
 also tighter than the comma. See L<operators> for more details.
