```c:\@Work\Perl\monks>perl -wMstrict -le
"my (\$x, \$y, \$z);
;;
(\$x, \$y, \$z) = qw( 1 2 3 );
print qq{\$x, \$y, \$z};
;;
((\$x, \$y, \$z) = qw( 1 2 3 )) = qw( a b c );
print qq{\$x, \$y, \$z};
;;
(((\$x, \$y, \$z) = qw( 1 2 3 )) = qw( a b c )) = qw(foo bar baz);
print qq{\$x, \$y, \$z};
"
1, 2, 3
a, b, c
foo, bar, baz

The expression  (\$x, \$y, \$z) = ... evaluates to a list of assignable values, i.e., lvalues.
The expression  (\$x, \$y, \$z) = RHS evaluates to the list of assignable values, i.e., lvalues, \$x, \$y, \$z.

And likewise with

```c:\@Work\Perl\monks>perl -wMstrict -le
"my (\$x, \$y, \$z) = qw( 1 2 3 );
print qq{\$x, \$y, \$z};
;;
(my (\$u, \$v, \$w) = qw( 1 2 3 )) = qw( a b c );
print qq{\$u, \$v, \$w};
;;
((my (\$r, \$s, \$t) = qw( 1 2 3 )) = qw( a b c )) = qw(foo bar baz);
print qq{\$r, \$s, \$t};
"
1, 2, 3
a, b, c
foo, bar, baz
