## Storing three integers in a variable in Perl 5 ##

my $a = [2, 4, 6];   # a scalar variable aliased to a reference to an ARRAY object containing three SCALAR objects
my @a = (2, 4, 6);   # an array variable aliased to an ARRAY object containing three SCALAR objects


## Storing three integers in a variable in Perl 6 ##

my $a = (2, 4, 6);           # an item variable bound to a Scalar object containing one Parcel object containing three Int objects
my $a = list 2, 4, 6;        # an item variable bound to a Scalar object containing one List object containing three Int objects
my $a = [2, 4, 6];           # an item variable bound to a Scalar object containing one Array object containing three Int objects
my $a = Array.new(2, 4, 6);  # ditto

my $a := 2, 4, 6;            # an item variable bound to a Parcel object containing three Int objects
my $a := (2, 4, 6);          # ditto
my $a := list 2, 4, 6;       # an item variable bound to a List object containing three Int objects
my $a := [2, 4, 6];          # ???
my $a := Array.new(2, 4, 6); # an item variable bound to an Array object containing three Int objects

my @a = 2, 4, 6;             # an array variable bound to an Array object containing three Int objects
my @a = (2, 4, 6);           # ditto
my @a = list 2, 4, 6;        # ditto
my @a = Array.new(2, 4, 6);  # ditto

my @a := 2, 4, 6;            # an array variable bound to a Parcel object containing three Int objects
my @a := (2, 4, 6);          # ditto
my @a := list 2, 4, 6;       # an array variable bound to a List object containing three Int objects
my @a := Array.new(2, 4, 6); # an array variable bound to an Array object containing three Int objects

# Also, in some of those cases the Array/List object will have the ":flattens" attribute set, and in others not (though I don't understand what governs that).
