or an array which is taken per reference, because of the prototype (like in shift)

Method calls are not influenced by prototypes 

sub Y::Pushy(\@){ warn join ' ', map {"($_)"} @_, ''; }
my @blah = 1 .. 2;
Y::Pushy @blah;
Y->Pushy(@blah);
__END__
(ARRAY(0x3d8bbc)) () at - line 2.
(Y) (1) (2) () at - line 2.
