There are many meanings for {}, for instance a code block.  In this
base we want the ref-hash meaning.  Perl is capable of correctly detect
which meaning the {} have... however, it is not always clear for the
reader of the program.  So, for clarity sake only, I often write +{}
-hash to be explicit that I create a ref-hash.

   my @a = (3, 4);
   my ($x, $y) = @a;   -> $x==3, $y==$4

   my ($v, $w) = \@a;  -> $v==[3,4], $w==undef

  @x is an array: storage for a list of values (not a ref)
 \@x is a reference to an array; where to find an array
