in reply to my $x or my ($x)
Here's a popular use of the list context:
sub foo { my ( $x, $y, $z ) = @_; # ... }
You can mix scalars with other types:
sub say { my ( $x, %param ) = @_; # ... } &say( "Hello", name => "world" );
The following example won't work as you could expect, because all the arrays will be flatenned into the same one:
sub bar { my ( @a, @b ) = @_; # wrong! # ... } &bar( @array1, @array2 ); # wrong!
The solution is to use references, but we still can use the list context:
sub bar { my ( $a_ref, $b_ref ) = @_; # ok # ... } &bar( \@array1, \@array2 ); # ok
