List constructors

Hi all,

reading [AS]02 left me a bit unclear on list construction. Specifically,
as comma still seems to be the list constructor, what do these produce:

    my $a       = (1, 2);   # a List object of 1, 2?
    my $a       = (1);      # Int 1?
    my $a       = (1,);     # List of 1?
    my ($a)     = (1, 2);   # Int 1? Or does it need *?
    my ($a,)    = (1, 2);   # Same as above, I hope...
    my ($a, $b) = (1);      # $a == 1, I presume

Also what do these rather esoteric cases do:

    my ()   = ();
    my $a   = ();
    my ($a) = ();

Syntax errors in a few of those are welcome. :)
